to correct value after seeking)

The internal player seems to get wrong frame counts for avis when starting
to play it. After seeking the frame count gets synched to a correct value.
This problem was revealed with a .avi and an external frame-based
subtitles: the subtitles were out of synch (about 1-2 secs too late) when
playing the file from the beginning, and got back to synch after seeking
once to some direction.
I started to track this problem, but ran out of (non-occupied backend)
time for now. I think the problem is that the framesPlayed is stored in
multiple different classes (NVP, Decoder, VideoOut) and they get out of
sync with each other at the beginning and the seeking syncs the correct
framesPlayed value to the VideoOut which is used by the text subtitle
display code at NVP. I also tried using the NVP framesPlayed instead of
the current videoOut's currentFrame framesPlayed for syncing the subs, but
it didn't help.
Anyways, if someone knows immediately what the problem can be, great.
Otherwise, I'll look into this later when I have time again. It doesn't
seem to affect anything but the syncing of frame-based external subs...
