That's becase the tv-tuner sends the picture direct to the video-board and it does not touch the video memory. SInce vnc just copies what's in video memory, that's what you get. > Anyone know how I can view live video through VNC? First: not. Second: may be but verry slow: If you can switch the direct access off from the tv-board to the video-board then the video has to get into video memory where vnc can read it. Then there is the processor power and bandwith in all the systems: Video data goes from tv-board to video-board. It will fill most pci busses. Hence the video on the local display will already drop in quality. Then you start vnc: that reads the same (or more) amount of data from the video board to the viewer. Don't count on compression at this stage, that is done by the processor, not by the video. So there will (at least with pci video-board) a real drop in quality, already on the local display. Then the data must be send to the viewer. Following the above, you don't want to view on a local display so it get's send over a network. Then the compression in vnc is not like mpeg or divx hence if it can get the information and process it, a 100 Mbit network wil be filled.... > > Please let me know.. If you get things go-ing, let us know the configuration and the quality....
