For the Video guys, Mark?

[Cyber Source]

One other question with this,
  I can record from the tuner card into an avi file and the video and
sound work now but there is alot of noise on the sound, really annoying
interference noise. I have tried all sorts of sound formats, 8bit mono,
16bit mono, stereo, nothing seems to change the sound quality, but the
files size change so it must be changing the sound format. After alot of
trial and error, I found that it will not record sound with igain muted
and it will not play sound via mplayer with pcm muted (i did see that
mplayer uses pcm as it's output so that is understandable) but I dont
understand this igain. I have tried lowering the volumes to help but the
noise is unchanged. Any ideas on this interference noise?
btw, this is using onboard sound (via8233) with ALSA.
I know about using onboard anything but all the mb's today come with
sound and using ALSA, they have been working flawlessly
