Sounds like you have udev rules that put devices in the right places, 
but that fail with the other cards--check those rules and update them 
for the swapped cards.  I don't know of any way swapping a PVR-250 for a 
PVR-250 could cause problems--so that means something else is causing a 
problem.  If you're saying the only problem you see after swapping them 
is mythbackend crashing, that means you're changing something 
mythbackend relies on, and mythbackend logs would tell you what that is.

 Hi Mike,

 
Yes - I do have UDEV Rules, I'll try removing those and swap the cards around again and see if the problem moves with the card.

 
Thanks for the pointer.

 
Dave.
