Personally...I love this myth TV deal, I just haven't had a chance or a spare box to setup soemthing yet. I have the Radeon ALL in Wonder and I have to admit the ability of this thing is astonishing, even though I don't use it as much as I should.
I'm still working towards an all in one box top solution -> pc gamer, emulator, tivo, music server, burner, not just to cut cost
(peicing a system like this together is still a bit costly compared to all in one solutions) but because of the Versatility of the system and i like computers. Besides PC games at full detail and resolution is just unbelievable compared to console games when hooked up to a HD set.
I'm gonna use my myth box as a tivo and mp3/media player/server. put a nice big hard drive up on it. I'll run a samba server on it so I can stream to my other windows computers.
it'll also host all my mame/nes/snes roms which work with myth ot-of-the-box, and I hope to get a n64 emulator running.
let me know how it works out
I remember reading that there were problems with using the Radeon All-In-Wonder with MythTV
