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.
