This almost sounds like you don't have the NVidia drivers installed so
Xv support can be used.  When you run mythfrontend, does it display a
message about "non-Xv mode enabled" or something to that effect?  It
sounds like you're doing software scaling and color conversion instead of
it being done in hardware by the video card if you had the proper drivers

You should be able to do 704x480 mpeg4 easily on your system.
