#868: [8350] breaks mpeg2 decoding during frame advance

Comment (by danielk):

 FYI The PVR-350 does not function in keyframe or half second advance, with
 or without the changes in [8350]; it plays the the video from the last
 keyframe at normal speed, and doesn't advance properly. It does work in
 frame-by-frame advance and for larger jumps.

 Fixed in v2 of the patch is the exit from FF/REW mode. This would jump to
 a semi-random location in the file if a newly decoded frame wasn't
 available and it had to use the scratch frame for the pause frame. This
 predates [8350], but needed fixing.

 Also fixed is the first backward seek in NUV files after a pause during
 playback, again this problem predates [8350], but needed fixing.

 Also fixed is seeking in non-PVR-x50 recordings, broken by [8414].

 Problem #1 from my previous note appears to effect all decoders. I need to
 generate a test video to figure out where the off-by-one error is...
