Hmmm, I would guess that udev is not working for you.  I would check
to make sure that /dev/video_PVR150 actually exists, and is a symlink
to /dev/videoX.  Once you have the dev working, Myth should accept it.

I do not have a PVR150, but I do have two HD-PVRs.  My rules actually look like:

SUBSYSTEM=="video4linux",ATTR{name}=="Hauppauge HD
SUBSYSTEM=="video4linux",ATTR{name}=="Hauppauge HD

You don't need to use the serial part, unless you are trying to
differentiate between two HD-PVRs.

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
