• check your config and options for 'framedrop' and disable/turn it off. try also -framedrop
• its possible your file is incomplete, try md5sum against the original or rehash it using your torrent program.

i want a concise comparison of the various options - say, their scores on performance measures - to help choose between em. instead there are a few sentences on the origin and implementation of each one.

• different vo's are faster/slower on different pc, drivers and video cards, its almost impossible to tell whats fastest for everyone.
• use mplayer -nosound -benchmark file -vo (vohere) to test your video output speed
• vo's with hardware accelerated output (like xv, vidix, directx, macosx/quartz) will usually be faster than vesa, fb, gl/gl2. but not always.
