Well, there's changed quite a lot in 0.7.3. Just to make things clear:

	FF = fast forward
	SF = slow forward
	FR = fast reverse (rewind)
	SR = slow reverse (rewind)

FF, FR and SR as well as moving cutting marks just play I-frames and 
there is a problem in VDR that sends incomplete I-frames to the devices. 
Especially when xine reports bad_frame on its controlling terminal then 
it is likely that the "bug" triggered.


addresses this issue. A proper solution will be supplied by 
cVideoRepacker but it seems to trigger other problems so it is disabled 
in recent VDR versions. The above patch will then still be necessary to 
edit old recordings properly which have been recorded without 

A known issue is that switching from pause or play to any of the above 
mentioned speeds will cause a delay of several seconds before playback 
at the new speed gets active. This issue is most noticeable on less 
powerful machines like my EPIA MII-6000E which has just a 600 MHz CPU, 
while it is not that much noticeable on my development PC which has a 
Pentium 4 HT processor which runs at 2.8 GHz.

To let me address your issue properly, would you please explain whether 
one of the above issues is what you experience or if it is a new issue.
