I would be surprised if it is the same hardware. most USB capture devices aren't. The reason is simple. The USB bus doesn't have the bandwidth, so there is a compression step done at the point of capture (usually a proprietary compression, hint hint), and then the windows driver will do the necessary decompression (and since it's a proprietary compression, the Linux driver won;t be able to do the decompression of the data stream). I believe that this is how the Win-TV USB device works. I would not be surprised to learn that the ATI USB device works similiarly. rgds, -Greg +---------------------------------------------------------------------+ "DOS Computers manufactured by companies such as IBM, Compaq, Tandy, and millions of others are by far the most popular, with about 70 million machines in use wordwide.
