gerald1624705841 Posted February 6, 2007 Posted February 6, 2007 I have a Oppo 970 with latest firmware connected to SR8001 via HDMI (though im using a CRT TV) Sometime the DVD plays without sound (Audio) but the same DVD sometime plays with Audio. After trying out a few times i found the problem to be like this. 1. If i on the Amp, put it to DVD and THEN play the DVD (in Oppo), there is picture but no audio 2. On the other hand, if i play the DVD (in Oppo) first, THEN switch on and put the Amp in DVD, there is BOTH picture and Audio - no problem at all. I understand it is a handshake problem. Like to hear from SR8001 and oppo 970 users if they encounter the same problem. Also if i buy a plasma TV with HDMI, am i gonna have the same problem with HDMI connection? Thk u.
dXter Posted February 6, 2007 Posted February 6, 2007 I don't own any of those but I had came across posts of similar issues from pple in avsforum who had sr7001/8001 with oppo970. They managed to get response from oppo's support that it's a handshake issue due to differing hdmi specs implementation. I guess you are not alone. The problem cannot be solved by oppo alone, both sides need to share and resolve it.
gerald1624705841 Posted February 6, 2007 Author Posted February 6, 2007 If i change to Oppo 981, wonder will i have the same issue?
Nstarone Posted February 6, 2007 Posted February 6, 2007 If i change to Oppo 981, wonder will i have the same issue? My Oppo 981 works fine with my SR8001 if it helps.
gerald1624705841 Posted February 6, 2007 Author Posted February 6, 2007 Nstarone, Is ur oppo 981 HDMI is connected to ur SR8001 HDMI or direct to ur display? My Oppo 981 works fine with my SR8001 if it helps.
HT102 Posted February 6, 2007 Posted February 6, 2007 I understand it is a handshake problem. Like to hear from SR8001 and oppo 970 users if they encounter the same problem. I have both the Oppo 970HD and SR8001 connected via HDMI. I do but rarely experienced suchs problems. Even when it occurs, the issue can easily be resolved by switching the source from say DVD to AUX1 and then back to DVD again. Perhaps that's because I usually turn on the DVDp first followed by AVR.. will verify tonite.
gerald1624705841 Posted February 6, 2007 Author Posted February 6, 2007 HT102 Thks. Verify and let me know. I believe ur Oppo HDMI is connected to your 8001 HDMI.

DIRTRUN Posted February 6, 2007 Posted February 6, 2007 Hi, Sorry a bit late to digest this...does this mean dat ur Marantz avr is doing the pic duties too in that u are putting all sources to de avr and then one hdmi out to ur display? Wat if those dat go straight, one hdmi cable to display and to avr an coaxial digital or optical input any sync problems wif that arrangement? Regards Dirtrun

Wat if those dat go straight, one hdmi cable to display and to avr an coaxial digital or optical input any sync problems wif that arrangement? Regards Dirtrun Hi dirtrun, My SR8001 is doing the switching (as in only one HDMI out to TV). My AVR connects to the Oppo 981 (HDMI), Starhub HD box (HDMI) and DVR (component). No problems for all. I did have occasional sync problems with my Oppo 981 in the beginning but after using firmware ver 1227, it went away. I also upgraded from the stock cable to a QED HDMI cable. Maybe that helped too. In theory, going HDMI straight to the TV (and coax or optical to the AVR) should be even less of a problem (unless you have incompatibility problems with your TV and the Oppo, which is rare).
SiriuslyCold Posted February 6, 2007 Posted February 6, 2007 Dirtrun that might work for SD players (DD/DTS etc) but it isn't a good solution for HD / BD player audio streams (DD+ and DTS-HD gets downsampled and reencoded as DTS if you force them out on the SPDIF)

But for sake of argument are there any new audio formats yet on de Hd discs or are they at de moment still peak at dts es 6.1 discrete? Sorry ah still on old genre avr here, hehehe Dirtrun

Hi bro N, I thought so too, but in future I guess tat would not be ideal...hehehe but 5.1 is enuff for most rooms Thanks Dirtrun
Jedi R Posted February 6, 2007 Posted February 6, 2007 Great to see so many people using the SR8001. I am thinking of getting one.. Any feedback on the SR8001 ?

Doggie Howser Posted February 6, 2007 Posted February 6, 2007 But for sake of argument are there any new audio formats yet on de Hd discs or are they at de moment still peak at dts es 6.1 discrete? Crank and Descent both have Discrete PCM (uncompressed) 6.1 PCM/Dolby TrueHD and DTS Lossless Master over HDMI support multichannel audio, which I think is expected to be 7.1 but can support more.

Wow, Sorry I dunno wat de first part means ... is de normal dvds compressed 6.1? I guess wat matters most is...Is there a discernable difference to de old 6.1 discrete? I would venture a guess to say not much if any in real world listening levels... Thanks Dirtrun
SiriuslyCold Posted February 8, 2007 Posted February 8, 2007 Yes, normal DD and DTS are compressed. Furthermore the compression algorithms are LOSSY, which means you lose some of the original information (like MP3, but much better) On some concert DVDs you can get a PCM stereo track that is uncompressed. Dolby TrueHD, and DTS-HD Master Audio are also compressed, but they are using a LOSSLESS method, being used in DVD-Audios. Lossless compression (like FLAC) means you do not lose data. Sometimes this is called PACKED PCM (PPCM) Uncompressed PCM takes up a lot of space (you can do the math 24bits x 96,000 samples per second x 8 channels x duration of soundtrack)
HT102 Posted February 8, 2007 Posted February 8, 2007 HT102 Thks. Verify and let me know. I believe ur Oppo HDMI is connected to your 8001 HDMI. Gerald, I'm afraid I could not reproduce the HDMI-connectivity problem regardless if I turn on the AVR first or later.
1AngMoh Posted February 9, 2007 Posted February 9, 2007 Crank and Descent both have Discrete PCM (uncompressed) 6.1 PCM/Dolby TrueHD and DTS Lossless Master over HDMI support multichannel audio, which I think is expected to be 7.1 but can support more. Yes, 8 audio channels are expected for Dolby TrueHD - but the standard does allow for more. According to 'Home Cinema' the new standard can output up to 14 audio channels simultaneously - not that the studios utilising this!! Dolby TrueHD, and DTS-HD Master Audio are also compressed, but they are using a LOSSLESS method, being used in DVD-Audios. Lossless compression (like FLAC) means you do not lose data. Sometimes this is called PACKED PCM (PPCM) Not sure that's strictly correct. My understanding is Dolby TrueHD is a 100% lossless coding technology and although DVD-A uses MLP lossless, various technical extensions and revisions were made to MLP for the Dolby TrueHD implementation. For example compared to MLP Lossless on DVD-A, True DolbyHD supports double the maximum bitrate (18Mb/s), double the number of possible channels (14) and more options for stereo support. TrueHD is also more efficient in compression. TrueHD promises to deliver higher quality audio than either DVD-A or SACD, though to be honest SiriuslyCold, i would take that promise with a pitch of salt. Even if true few people would own the hardware required to hear the difference.
gerald1624705841 Posted February 9, 2007 Author Posted February 9, 2007 Hi HT102 Thk u. Is ur avr connected to display via HDMI too? Bec im using a crt tv. Guess i have to go the component way to connect my Oppo 970 to 8001. Thks Gerald, I'm afraid I could not reproduce the HDMI-connectivity problem regardless if I turn on the AVR first or later.

Thks There is no display connected currently as I am waiting for the local availability of my desired front projector. However, previously when it was connected via HDMI to a BenQ PE7700, I did experience occasional handshaking issues when I turn Off or On the projector. The "handshaking" usually takes 3-5 seconds (no audio is heard). However there were a handful of occassions when the absence of audio persisted and "No Data" is displayed on the AVR, which I can easily resolve by switching back and forth the source selection on the AVR. Ever since I had my set changed by WKH (due to "static shock" issue, ref to a previous thread in this forum) , I have yet experienced any handshake problem. Note that all this while no display is connected, with the DVDP and AVR connected via the HDMI cable supplied by Oppo. I do however suspect my previous handshake issues were related to the lesser quality 15 metre HDMI cable (costs only $200+, with non-gold plated connectors) I used with the projector.
gerald1624705841 Posted February 10, 2007 Author Posted February 10, 2007 Thks HT102 for your detailed explanation. Currently im not in Singapore and could not tweak or try out alternative connections or try switching back and froth the source selection on the AVR (8001). I will get back to Sg on 13th Feb and may seek ur assistance if i could not get it right and if u r ok with it. Still makes me wonder why my oppo 970/8001 has problem while u dont have with ur oppo 970/8001 combination! Thks again HT102.

kurchan Posted February 26, 2007 Posted February 26, 2007 I also have a same problem with you but my combination is 981/Palladine 3200M. For time being, i just try to change upscaling back and forth from 1080i --> 1080p --> 420p --> 720p --> 1080i. It's quite troublesome, anyway. Anyone has same experience with combie 981/Palladine 3200M? How to manage this issue? Thks HT102 for your detailed explanation.
