As I am typing this I am watching TV on my FreeBSD box 8) Whats different is that Matrox Meteor is dumping video directly to my video graphic card very little CPU intervention. The reason for the very little intervention is that the program "tv" is capturing a single frame at a time. So right now I am watching tv at 640*480*4 at 30 fps or there abouts. the bottom line it looks damn good!! I will release a new version of "tv" tomorrow and will send out appropiate patches for the meteor driver. > > How do you deal with bus-to-bus DMA cache effects?

I still can't answer your question however the program seems to be behaving quite well. --- "TV -- It Came From FreeBSD " (Just finished watching : "It came from outer Space II" Enjoy, Amancio
