Media center software for Linux

So my fucking Xbox just crapped out (or perhaps just the modchip), leaving me without my beloved Xbox Media Center.

What I'm wonder is if there as any XBMC-like software that I could just run on my fileserver and use via TV-out and a PC remote control.  Preferrably something Mplayer-based.

Can something like MythTV be installed and used simply for its media-playing abilities and not all that Tivo crap?

Any suggestions would be appreciated.

i tried geexbox. it was really neat and i liked it a lot, but it crashed all the time. maybe it wont for you though. its only a like 9 megs and easy to config.

also there is movix (google it), which is similar but i have not tried.

personally, i just ssh into the box with the big monitor (thus should work for tv out too) and run my anime on mplayer using the vesa output so it displays it on the monitor and not my laptop. then i can control it all like normal from my laptop.

>>2 im pretty sure ffdshow is based off the mplayer mpeg4 decoder. it can do all that stuff too.
