[mythtv] frontend crash w/ ff/rewind on divx files (seems ok with rtjpeg) w/ cvs from 11-30-03

[Rick Warner]

When fast forwarding or rewinding on divx encoded files, i get seg faults.  
Encoding is being done w/ divx at 640x480 at 2200kbps and mp3 sound at quality 
5.  System is a dual athlon.  Let me know if more info is needed.

Backtrace:
