My assumption was that by upscaling/upconverting, the OP meant some sort 
of enhancement of the original image to beyond simple scaling to the 
native display size.  My understanding is that this is what the 
upscaling DVD players claim to do.

They cannot create image data that doesn't exist in the original, but 
they can do some fancy-schmancy stuff to improve the image on the larger 
display.  (At least I think this is what they do.) This is what I meant 
by, "MythDVD doesn't do this, to my knowledge."

It - along with X - does a great job with simply scaling to the native 
display size.  480p DVDs look identically wonderful on my 1080p set 
whether played through my standalone DVD player or through Myth.
