Oringally had an ATI Radeon 9200, dropped that pretty fast and almost gave up, found a GeForce MX 4000 for 26 bucks , grabbed it, still woouldn't work. Kept getting a white screen after the NVIDIA logo.
Went into XFree-4 and changed the driver to vesa which let me in, and after MUCH messing around i downloaded to newest NVIDIA drivers and w00t it all worked. Uncommented the options for TV-out and i was on my way.
A note to anyone who is having problems, DO NOT GIVE UP, this is so worth it when it finally works this thing is damn near perfect. just have to get the guide font bigger
I love the mythweb and streaming recordings.
