"- 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?"
