Hello Mike,
  Thanks for getting back to me. I fully know how mythtv works, 
backend/frontend, etc.. In my frustation, shorter emails go out, ya 
know? Anyway, when your watching tv and you select "m", it takes you to 
the schedule and show the current channel in the upper right corner (if 
that's your option). Then when you hit enter and decide to record that 
running show, it will change to recording (and watching) the selection 
you just made because when your recording you can't watch another 
channel, etc. It's at that point that my screen goes black, no sound no 
anything. I can hear the drive crunching, look in the directory that the 
recording is going into, and watch it grow, just it is only recording a 
black screen, no video, no audio. I have started mythfrontend with -v 
all option and looking at that see that it is bitching about audio rates 
that it wants and cant have and that it is dropping frames, so I suspect 
that it's a sound issue. I had it configured with the onboard via sound 
card, then installed a sound blaster live, still same results. Sound 
works fine for watching tv and all other sound functions. Also, if I run 
"cat /dev/video0 > /tmp/someshow.mpg, it records beautifully with sound, 
etc. I must have some setting wrong in my myth record options but this 
is a pvr-350 and initially thought I had something wrong with the ivtv 
modules. I have
AMD 3000+, FC4, 512MB RAM, 2.6.13-1352 kernel with all options installed 
as per wilsonet.com/mythtv.
Not real familiar with ivtv, I thought that maybe it was trying to 
record using a different device node, whatever. At this point I am 
really frustrated, any thoughts? TIA
