[mythtv-users] Can't cope with crowds or loud noise! PLEASE HELP

[Bill Chmura]

I am having a similar problem on a PVR350 when I record some shows for my 
daughter.  At different spots throughout the recording it makes a very loud 
crackling static noise at a higher than normal volumes.

The only real difference is that these are recorded on the Di$ney channel and 
are at low resolution.  I am also having a problem with vertical bars on the 
picture at low resolution.

Per some of the postings in the archives, I made sure I was using PS, checked 
the volume controls and tried playing back a recording on mplayer instead.  
In mplayer the noise problem goes away, but the picture still looks poor.

I do not remember this happening with low quality recordings before...  I have 
been running mythcvs for a long time.  This is a build from a few days ago.

Something else I noticed is that the high quality resolution is at 
720xsomething, while low quality is set at 420x420 (the numbers I could have 
wrong, but they are a square)... should these be different?

I have not touched the ivtv drivers 0.1.9 since I got them working awhile 
back...

Thanks

Bill
