I plan on working the MythTV problem for myself as time permits this
weekend.  Something in the MPEGRecorder class in mpegrecorder.cpp
probably needs to be fixed.  I doubt lengthening the select timeout will
work - the one that's there is already pretty long. 

My plan is to turn on debug flags for ivtv and cx18 modules and do a
differential comparison, to figure out where MythTV's MPEGRecorder class
may be failing to set up the cx18 properly.

If I can find and fix the problem, I'll post a MythTV patch here.

Hmm.  My computer sometimes, but rarely, does that with mplayer and ivtv
after a brief period of high cpu load during playback.  I have never
encountered it with ivtv and MythTV - go figure.  I have a dual-core
processor so maybe that makes a difference with mplayer - I don't know.
