But what's video32 for then?) according to ivtv-detect, once of them is a YUV grabber and the other one puts out PCM audio data. i have not been able to use the YUV output with myth yet, because the v4l2 capabilities for the card do not appear to include V4L2_CAP_STREAMING, which is apparently important to have. haven't played with the PCM output yet. > > > > 4) How come the card seems to "stop" or go into some kind of idle mode when > > not used for a while?
