My problems with the PVR-500 have mainly been around channels 42-45.  45 is the
worst, but 42 & 43 have visible interference as well.

(It's a real pisser that three of those four channels are among my most
frequently watched.  The problem is bad enough that I've switched back to a
PVR-150.  Better to have one tuner that works well than two that don't.)
