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
