I tried commenting out av_remove_stream, but still get the problem.  It 
does seem like the problem is less frequent.  Only happens (so far) when 
watching live tv.  I still must say mythtv rocks!

My System:
I'm using 2 pchdtv (hd-3000).   Watching free over the air ATSC.  My 
backend is a 1.8 Athlon.  Connected to 3.2 P4 via 100 Mbps LAN.  With my 
old setup playback was flawless.

Things I changed...
Kernel: from 2.6.10 to 2.6.11
mythtv: from .17 to .18
Driver: from pchdtv2.0 (v4l) to pchdtv2.0 (dvb)
