For the audio settings, I've tried everything I could think of.  I have
the audio from the TV card run out and into the Line In on the card.  I've
also tried it on the Mic.  I have capture turned on on line in (or mic
when nessessary) and capture turned on on the Capture setting.  I have
tried every combination of mute/unmute on capture and line in (mic) I have
basically put every other setting in the mixer at max volume and unmuted.

I have done the recording as both default and LiveTV.  Both of which I
have switched between RTjpeg and MPEG multiple times with the same effect.
 I have tried all the settings for sampling rate 32-48Khz with different
levels of MP3 quality.  How do you set it for raw?  I don't remember
seeing that option.

Here is a sample of my logging from mythbackend when I do a recording:

2004-03-14 17:21:25 adding: waes as a client (events: 0)

I did find the message "strange error flushing buffer..." sporadically
through the log:

2004-03-13 23:25:06 Started recording ".Hack/Sign" on channel: 2054 on

strange error flushing buffer ...

I have done this many times with every setting I can think of.

I'm going to try playing around some more tonight with more settings.  I
took a couple day break because I was getting frustrated.

Thanks for your help.
