The SA boxes do have a digitizer. I didn't notice any differences between their analog image quality and other boxes' image quality, though. I've never even seen a HD Explorer, so they might be different. A low signal, however, can strain a bad analog design. If you're REALLY interested in what these boxes can do, you can look at: http://www.powertv.com/Developers/PubDocs/pubDocs.shtml And look at the PowerDraw and Capture documentation. PowerTV is the OS running on these boxes, and the API documentation can give you a glimpse into what they can do. (32 bit RGBA color, a built in video scaler, etc. The development boxes used to have an ethernet port, and there's an ftp server available for them... You could see folks running them on ethernet at trade shows). I'm not sure how the alpha blending is done in full screen mode (when the video isn't being scaled). It should be possible to combine the analog signal with the signal from the graphics hardware (people used to do stuff like that with Amigas, and the documentation manetions video passthrough modes), but since the video capture features only work at 16 bit color modes, I'd be surprised if the box always digitized the image just to let you watch TV. -Ori Pessach -Ori Pessach Trevor Boicey wrote: > Ori Pessach wrote: > > Are you sure it doesn't digitize it?
