Does anyone know what could be wrong here? I can't figure out what's wrong. I tried using "azap -r CALLSIGN" and mplayer with the '-' switch to play the DVB stream and it works fine! With all the channels that are broken in MythTV. Myth doesn't play it smoothly and I only show like 25-35% CPU usage. The audio sounds like it has glitches in it and the video is stop and go. It's really bumming me out. I'm currently running CVS from 4/3.
I just need some suggestions or something,
--- Running Conditions ---
939pin Athlon64 3200+
OS - Standard Issue Debian (32-bit)
MythTV - CVS Version (4/3/2005)
Capture Card - pcHDTV HD-3000
Drivers - Using DVB (kernel 2.6.12)
