Hi! So here is a new patch. Take a look I don't claim it is perfect or beutifull, but it seems to fix some movies, and not break too many (none that I know of). rv30 and rv40 videos should benefit from this, rv20/rv10 might be a bit worse in some cases - i will try to fix those later. btw it seems there are discontinuities in some of these videos - hence the desync before. I don't know if it is a feature or a bug in the file, or realplayer can play those, or if realmedia can play those only because it is not trying to change a-v sync smoothly (as mplayer does without -mc 5 afaik). If you have any ideas about this, tell me! hehe rc4 flamecounter. i have been watching these streams for the last ten hours, so some flaming would really help me release the steam now. maybe not. bye Denes the movies I tried from the samples seems to be fixed (-mc 5 is usually a good idea though, because of some apparent discontinuities in the videos): -rv30 90009885H.rm (tron trailer) av_out_of_sync_after_about_10_minutes.rm (-mc 5 is needed at cca. 450 secs) Episode 603 - Asspen.rm (-mc 5 is needed or audio won't catch up) pnm://rm.bbc.net.uk/news/olmedia/cta/progs/02/click_online/03oct.rm pnm://rm.bbc.net.uk/news/olmedia/cta/events03/war_on_terror/powell26jan.rm ( -mc 5 or something is needed, or it takes 30 seconds for the audio to catch up) -rv40 (these work without -mc anything) SirMixalot_-_Baby_Got_Back-uncensored_version(sm).rm (used to play too slow) Blade2_640_1Mbps.rm (picture is not perfect, but perfectly synced with audio) broken (rv30): 141a.rm (there is kind of constant delay, I don't know why/ how to fix it)
