When browsing through the channels with the zapOSD the starttime is displayed. Now when you stop browsing and MP tunes then the starttime moves a little to the right. See: http://home.ict.nl/~mweterin/mp/weird_moving.png The bottom part is before tuning, the top part is after tuning.

ZapOSD settings are:
 - Zap delay = 2
 - Zap timeout = 5

Tried on MCE and Metal with VMR9 and tiemshifting on
