Just curious, does your application require the MPEG encoder or will you always be doing encoding of raw video yourself with low latency being your critical need? If you have no need for the MPEG functionality and need reliable low latency video capture, you would probably be better off with a bt8x8 or cx88 based capture card - They work INCREDIBLY well if you don't need hardware MPEG encoding and have very low latency. (Suitable for playing console games, low latency videoconferencing, etc.) The PVR-150 wasn't really designed to provide raw YUV - it happens to do so but it is essentially a design afterthought that has low priority with both Hauppauge's engineers and most of the ivtv people. Cards that use the bttv or cx88 drivers, on the other hand, do nothing but raw video capture. bttv and cx88 cards also happen to be significantly cheaper - I've heard of people getting tunerless cx88-based boards for $20-30 USD. Too late for your current system, but if you are planning multiple systems with capture boards down the line it could make a big difference. _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
