Right. I just went through this over the weekend.

I have the (2) pcHDTV cards and my PVR-350.

While Myth uses /dev/dvb for the pcHDTV cards, video4linux still assigns them a /dev/video number which can muck up where the PVR-350 goes.

Soooo, the PVR-350 is now mapped to /dev/video-pvr350.

I had to specifically tell Myth not to use /dev/video0 (which is still valid) but to keep scrolling through the list in myth-setup until you get the one that's the new symlink.
