Does anyone have pixelation problems in SD while watching programs mainly on 7. I find all the other channels are fine but a lot of programs on 7 at night seem to now and then.

Nope and when I did it was my crappy outside (bunnings) antenna. After having Jim's Antenna put a new one up, my reception has been perfect.

Till then I would have block problems, audio pop's, a frezze frame etc, thing was it only happened now and then and sometimes worse on one station or another. But 98% of the time all was great, as such I started to blame the TV Stations, yet (aside from one or two station problems) it was all me.

Now while Jim wasn't cheap, spent the money once and never had a problem since.

We've mainly found that certain shows are looking pretty crappy, particularly on SD - Enterprise on Channel 9 SD in particular looks like it has been compressed to VCD quality most of the time. Other shows, from across all the different channels, look fine to me most of the time.

hmm, thats strange then, because I just watched a recording of Enterprise (on too late when one has work the next day, got to love that toppy :blink: , and it looked pretty darn good and that was on SD, way better then VCD quality.

At one point I did a small grab and transfer/encode of its HD broadcast, and that looked just bloody amazing.

With my Pana QTR2140, I was getting pixellation problems on seven quite regularly especially at night, all other channels were OK.

I've since bought a Teac DV-B350 and had no problems since, it seems as if the Pana box was more susceptible to this. The signal strength on seven was always about 10% below the others at my place, this could have had something to do with it.

I get my signals from a translator (Newland Hill) BTW.

Well, maybe I was exaggerating a bit when I wrote "VCD quality". :P

However, I do still find a noticeable difference between Enterprise and some other shows - it is most obvious when there is a closeup of someone's face and they then turn their head, showing quite a few MPEG compression/motion artifacts. This is evident to me in both playback on the PC, and playback on the TV via a Neuston MC-500.

It may be that Ch9 are compressing the SD channel higher and giving more bandwidth to the HD one in this case - though shows like CSI dont appear to show the same artifacts and they have a very high quality HD version being broadcast at the same time.

It may also just be that I'm nuts. (Though the "boss" complains about Enterprise too). :P

Enterprise has a lot of large grain (SD or HD) and is not as crisp as most programs. The almost smearing effect on faces is there in the originals, so I wouldn't say its all 100% MPEG related.

Nine SD in Adelaide has a very decent SD bitrate already. Even transmitting SD at 8mbits won't give a noticeable quality boost anything over 6mbits is a waste of bandwidth. Watch the HD version and watch all your shows on Nine HD if possible because the upconversion will be better 99% of the time.

I don't get artifacts on Enterprise HD but the picture doesn't have the crispness or detail I've come to expect from HD.

On the next Enterprise ep, I'll have a much, very close look on the SD version to compare.

I wonder when you'll get a chance, as I've just noticed that Ch9 appear to have taken Enterprise off - or at least moved it to a different timeslot. I'll be quite annoyed if they moved it to last night.

Voyager was on last night but Enterprise has been taken off to make way for The Dead Zone :blink:

yeah, I noticed that, kinda makes having a closer look a bit of a problem and if the local TV guide is correct, then its not on next Wednesday either and can't see it listed for any other time.

O'well, a friend is getting season 3 off the net and I already have the first few eps for season 4. So given that they did this type of sh*t, then I find it hard to beleive that anyone wonders why ppl are turning away from our local FTA.

The only reason I haven't downloaded Enterprise is because Nine will eventually show it in HD.

Actually the HDTV encodes on the net are pretty good, not in HD res of course, but still, not bad. Besides, at the rate 9 work, chances are you will be able to buy them in HD sooner :blink:

If youre getting reception problems and you don't wanna fork out lots for new rigging, I would suggest trying the Digitor amplified antenna from Dick Smith (on sale now for $39). It's solved all my reception problems and guarantees me a 100% signal 24hrs a day. Basically what happens is you turn the gain up and the signal strength+quality go up like hell! I have gain set to about 30% which achieves 100% signals at all times, so if you've got a particularly weak signal then even more gain should definitely help.
