Thanks for your response.  That's what I suspected, but I wanted to be 
sure before I got drastic.

The box that the PVRs are in is a bit overloaded, IRQ-wise.  I had to 
add an IDE controller, video, sound, and LAN, just to get started. 
Despite disabling the on-board IDE (udma33), I suspect its taking up 
IRQs.  I was already thinking about moving MythTv to another, more 
modern box.  Guess I'll just have to do it!
