Yes, they both encode mpeg2 with hardware codecs. Except the DirecTiVo, which just receives mpeg2 streams from DirecTV. > I am using an old Hauppauge card that doesn't do any encoding of it's > own and I know that the ATI cards do compression on the card but it is > only mpeg2 are there other cards that do this on the card but using > mpeg4 so that I could use a slower processor? I am unaware of any ATi card with hardware mpeg compression. ATi will tell you right to your face that their cards have hardware decompression, but they do not. They implement a bilinear scaler and include a hardware assist for motion compensation (which is a niceity that makes deinterlacing prettier). afaik they don't even do an iDCT assist in hardware, and even that wouldn't really make it decompression. fwiw, the VIA MiniITX boards don't have a hardware decoder either. They offer more assistance than the ATi cards, but it's not anything like a DXR3 type card where you just stream mpeg2-pes to a pci card. For more than the cost of a new TiVo, you can get an ivtv based card such as the Hauppauge PVR350 and record mpeg2 in hardware. I keep hearing that mpeg4 boards are available, but I haven't actually seen any details. And I'm a guy with an ATSC encoder card on his desk at work. ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
