I guess one of the promises of upnp is the abilty for any client with
a upnp stack and a media player to watch recordings and videos, using
whatever player is efficient on that client. Other players may still
support xvmc.

There is also the flash streaming available in mythweb.

No you don't get a full frontend, but if these are not the main living
room experience, you may be able to live with that.

Come to think of it xvmc has a usable front end, i don't know if they
still (or ever) support xvmc, but it could be worth exploring.
