I think you are one of my favorite beta testers ;-). 

But back to the problem: 
Does the video plays good for you at that position(5265/25=210.6s)?
I remember having an issue with the caches and large frames (typically I-
frames) so if one I-frame is not correct, the video would look crappy at this 
position and the following P-frames (mostly 63 frames). Maybe I have not 
applied the patch to solve that. Ill gonna have a look this evening.
