I think your answer will be, "you can't." No. The answer is to do overlay using streaming capture & v4l2_buffer.memory = V4L2_MEMORY_OVERLAY instead of using VIDIOC_OVERLAY > > > Say someone wanted to start four instances of xawtv on > > > one device and have each overlay one of the time domain multiplexed channels > > > into a different window? > > > > That isn't going to work.

Not the current ones, thats pretty normal for new interfaces :) It likely doesn't make sense to use that for TV-orientated applications like xawtv or mencoder, because for watching and recording movies you probably want the full 25/30 fps frame rate (and also the sound ...). It makes sense for systems where you have multiple cameras connected to one grabber card, want use them all but don't need high frame rates. webcams, monitoring systems, whatever.
