It seems that the easiest solution here is to create
capturecard.profilegroup and recordingprofile.group.  With those two
fields, profiles we can select profiles by name, and look up the correct
one by which one maps to the card that we're using.  (I suppose you also
need a new table containing the currently defined groups, but it is only
useful for the selection interface, and is irrelevant as far as recording
goes).  We can then add record.profile, which stores the profile name. 
then in tv_rec, it is a simple (in pseudo-sql) 'SELECT
recordingprofile.id where recordingprofile.name = record.name (or
Defalut/Live-TV) and recordingprofile.group = capturecard.profilegroup'
and no other changes are needed to the recording code.
After that all changes are just GUI changes (determine how to associate
the group with the card, create new profiles whenever a group is created,
add profile-selection when selecting a recording, etc)

So the guts of the change is trivial, and it all falls onto setting up
the gui.  I think I am competant enough to do most of the gui work (not
sure about the best way to select multiple cards for a given group...i
assume a list box would be acceptable...but it gets tricky.  For
instance, you need to prevent a user for adding a bttv and PVR250 to the
same group (as the settings will be incompatible).  I'll give it a shot
and see how it goes, but since this has basically boiled down to a
user-interface problem, I'm perfectly happy to defer to someone who knows
what they are doing in that arena, if someone else feels like giving it a
go.

It seems to me that the Default and LiveTV profiles should remain, with
two additional 'High-Quality' and 'Low-Quality' being added (ignore
transcoding for now).  But perhaps we'd prefer to have 'Ultra-High',
'High', 'Medium', and 'Low' profiles, and then associate LiveTV and
Default to one of those per card.  It is a little more flexible, but
seems a bit overly complex.
