I don't know if it is at all related, but I have a similar problem
using uPNP with a PS3 and in progress HD recordings. If I watch a
previously recorded (and comm-flagged) HD recording on the PS3, I have
no problems jumping X minutes around the recording. If I watch an in
progress HD recording that is not being comm-flagged (usually hockey,
3+ hours) if I try to jump forward 2 minutes, it takes about 3.5 to 4
minutes to do the jump. I don't think it is the broadcast, because it
did it on both NBC and CBC last night, and pretty much every game I've
watched. It does not do it with SD material.

I am running SVN trunk, no EIT.
