There was a report on the linux-media list in July about being able to 
get one or other but not both tuners working, followed by a statement 
that it was working using 'twoflower' - whatever that is.  You may be 
able to follow that up.

I would be inclined to use the card setup page in mythtvsetup and see if 
it still recognises the two dvb-t devices.  If it does, delete all 
tuners, re-install them, define them as inputs and rescan using the 
technique I linked earlier.  Googling  some more about the specific 
device, or asking here with it in the subject line, might be helpful too.
