[mythtv-users] pvr 150 and pchdtv 5500 wont play together

[les]

have myth box with a 150 and 5500 cards..  if either one of the cards is 
plugged in everything works fine.
if both plugged in only one card shows up in dmesg.  (pvr 150)

1. do i need to create /dev/video1 .  for the second card to be detected ?
2. is this just a matter of switching the cards in there slots ?

have second myth box with pvr350 and hd5500 and it works great.. same 
myth ver. too.
must be something with the pvr150..  same motherboard too.
