What's Different About Ch 9 And Abc ?

[scottb7211503559952]

I have a HTPC that's been working fine since mid last year.

Last couple of months I've had problems with sync but only on Ch9 and ABC. I don't seem to have problems with 9 HD though.

I'm out at Nelson Bay but using the Newy transmission.

Is there something perculiar about these 2 stations, compared to the rest, that may be causing the sync issues ?

Thanks
