I have no experience of bt8x8 cards but my Marvel has a Philips and
gives an excellent picture.

That's the official spec, but with the right motherboard etc. you may

Full PAL mjpeg about 14GB. Half PAL mjpeg less than half that. you

I get mjpeg which is excellent, almost as good as the broadcast.
