fix problem with not appearing still frames on DVDs

(detailed problem description: since the flush is asynchroneous now and stillframes
will only show up, when flushed out of libmpeg2, problems arise on stills with
audio, where the video decoder waits for an audio discontinuity, which is all the
way down on the bottom of the audio fifo; video_out can now put flush requests on
the video fifo, but they won't get processed)
