I've not seen the segfault problem, but I do see very bad results 
running mythcommflag on xvid AVI files; fast forward or rewind ends up 
with a partially painted frame for a few seconds, with parts of the 
frame retained from before the FF/RW, until it hits the next keyframe. 
Is that the same failure mode you're seeing?

I wonder if anyone can comment about this possibly having been fixed in 
trunk already? (I'm also using 0.20.2)
