Folks,
I get consistent poor quality tv playback on my new mythtv
frontend. These problems are twofold. First, the quality is just
crummy, with horizontal lines as if it was getting poor reception off
the air. The second is that there are a lot of decoding glitches,
like areas of picture not updating when they should so there is a
distorted picture. I can play back the same recordings on my windows
machine, and they don't show either the general poor quality, or the
decoding distortion, so I believe it is really a playback problem.
Also, I can play back divx videos (such as ripped dvds) on the
mythbox and they come out very clean and sharp. I'm wondering where
I should start troubleshooting this? The video card is an on-board
SiS that has an mpeg2 decoder. I'm wondering if maybe it's using the
hardware decoder which may not be the best? If so, is there a way to
get it to not use the onboard decoder and decode in software as it is
with the divx?
Any suggestions would be appreciated!
Thanks,
Peter Darley
