I have a couple of HD-PVRs in use with a 3.11.2 kernel.

$ uname -a
Linux sapphire 3.11.2-201.fc19.x86_64 #1 SMP Fri Sep 27 19:20:55 UTC 2013

$ sudo grep hdpvr /var/log/messages

interface driver hdpvr

My only guess is that for some reason the hdpvr driver module is not
getting loaded (or is not available).  What happens if you do:
$ sudo modprobe -v hdpvr
