Another possibility is that you are using the wrong version of ivtv. 
Check at the ivtv site for specific information about which version runs 
with which kernel. You mention that you have updated things to a new 
kernel...which indicates you should be running the .6 version of ivtv.

To check, run 'dmesg | more' in a console and look carefully at the 
output between the ivtv markers. Ivtv is quite good at presenting useful 
debugging information. You should have 2 large sections, one for each 
tuner in the PVR500.

One possibility is that your modprobe.conf file is not correct. Do you 
get /dev/video0 and /dev/video1?
