[mythtv-users] poor audio and video

[Thomas Baker]

I have two problems that may or may not be related, one with poor audio 
and another with poor video.  I'm using Fedroa Core 4 64-bit and 
everything runs beautifully in TvTime, however, when I play "live" tv in 
MythTv, the audio only plays out of one speaker and the quality of the 
sound is sub-par.  By this I mean there is a little bit of static and 
frequent "pops".  I have played around a lot with alsamixer with the 
levels, and to get this question out of the way, yes my line in is muted 
and set as the capture.  I have set the volumes on "Master" and "PCM" to 
around 75% to assure teh audio is not peaking out.  "Capture" is set to 
0% (not mutable) because there is even more static and overall "tinny" 
quallity when it is raised (still one speaker only).  "Wave" is turned 
up as well as the "AC97 Capture" is turned up (not sure why these in 
particular, but with experimentation, I don't get any of the recorded 
audio without them).  As for the video, the overall picture quality is 
poor.  excluding the brightness, contrast, colour and hue, the picutre 
has a lot of thin horizontal lines in it.  It seems like once MythTV 
takes in the captured media, it just butchers the quality.  These right 
now are my two biggest problems and would appreciate any help I can get 
with this. 

Thanks,

Tom
