You can try any player you like, but you'll get the same result.  XVMC
means the decoding is done on the card, so the player can't do any
postprocessing to the video at all.  

You can always re-encode the video (non-realtime) with mencoder to
mpeg2, using the deinterlacer and other filters, then play the output
file.  Using "keyint=1" (and pretty much no other lavcopts) mpeg2
encoding can be quite fast, although the output will be very large.

I doubt your performance with a 3.4GHz Intel would be any better
than with your Sempron 3300.

You should be able to get playback up to realtime, even with
deinterlacing...  Use "-framedrop", aggressive values for "-vf
decimate", "-nocache", etc. Oh yes, and Rich's favorite... compile
mplayer with gcc-2.95.x to get libmpeg2 to perform much better.  After
that, you _might_ even want to try overclocking the processor/RAM
slightly.

I'm sure others here will have even more suggestions.
