[mythtv-users] Both cards are in use"

[Edward]

I have a pvr-500 and I can't watch or record, due to both cards are in use
when I try to veiw.  Thi sis my second time setting up a mythtv box and in
this case everythign looks ok.  I have the data from the zap2it and also I
can scan for chanels and they appear to get all of them and even not get
chanels from my cable provider that do not have data on them.

Where am I missing something?
