Comment (by Marcus):

 I've done some more experiments too see what's happening. When I
 fastforward > 3x, I get errors. Sometimes I just see artifacts in the
 image (boxes of contents appearing where it shouldn't appear). My guess is
 that this is mpeg artifacts caused by bad mpeg captured by my PVR-150 or
 bad decoding. Sometimes, however, the video starts jumping in time,
 showing pictures from the beginning of the video when I should be
 somewhere in the middle. And when I stop fastforwarding I found myself at
 a position earlier than where I started.

 I don't know much about MPEG but maybe it's some artifact in the mpeg
 (decoding) that sometimes just appears as block artifacts in the picture
 and sometimes garbles the timing of the whole playback?

 Note: I have never seen any problems during ordinary play, 3x ffw, or
 using 0.18.
