Note that many (all?) PVR-350s contain SAA7129 rather than 7127, and the
7129 has dedicated RGB/Cr-Y-Cb outputs.

I only got as far as noting that these RGB pins didn't seem to go anywhere
useful. Unless your PCB is different from mine, you'd have to connect to
the pins directly, which can be slightly fiddly. But if that has been done,
I can't see anything that prevents the use of this output... as long as you
remember to modify the saa7127.ko module so it configures the SAA7129
correctly.

The 7129 datasheet is here:
