>Possible reasons, problems, workarounds:
>- Most common: broken/buggy _audio_ driver
>  - Try -ao sdl or use the OSS emulation of ALSA.
>  - Experiment with different values for -autosync, 30 is a good start.
>- Slow video output
>  - Try a different -vo driver (-vo help for a list) or try -framedrop!
>- Slow CPU
>  - Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
>    e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
>- Broken file
>  - Try various combinations of -nobps -ni -forceidx -mc 0.
>- Slow media (NFS/SMB mounts, DVD, VCD etc)
>  - Try -cache 8192.
>- Are you using -cache to play a non-interleaved AVI file?
>  - Try -nocache.
>Read DOCS/HTML/en/video.html for tuning/speedup tips.
>If none of this helps you, read DOCS/HTML/en/bugreports.html.
