Anyone tested blueray players or mediacenters (Tvix, popcornhour etc)?

Any musical non-Linn DVDplayer that upscale to HD?
Apparently Unidisk cant upscale...

I'm wondering about this too, but if there are none, can you take the signal all five channels digitally out to your classik movie, and get a high result that way? Movie Di, i'm thinking about at the moment as a solution for a friend.
