Hi,

looks nice, thanks for the efford. Just as short comments:

for "gmc", it's misleading to call them "Sprite Frames", although 
technically they might be. But Sprites are a feature of Main Profile only, 
and these are either "GMC-frames", "S(GMC)-VOPs" or just don't call them 
anything. 

for "reduced" you might warn that the bitstream created is outside any 
MPEG-4 profile, and it most likely won't be decoded by anything else than 
XviD (does libavcodec support reduced resolution?). 

"mod_quant" isn't legal MPEG-4, though it usually works. 

for max_bframes>1, qpel and gmc you can warn that using those, though 
being perfectly legal MPEG-4, are not compatible to the "DivX Home 
Theater" profile, so the resulting bitstream might not be playable with 
(older) MPEG-4 standalone devices. 

Of course, similar restriction apply to lavcodec's mpeg4, so maybe a 
separate section on MPEG-4 + hardware-compatability would be useful. 

And have you thought of splitting mplayer/mencoder manpage into two?
