As far as I can tell, the only REAL issue here is that the column that
describes the type of data received is defined at the CARD level, and in
the case being described above I understand that the data-type is
different at the INPUT level (after all, the daughter board is actually
another input on the same card.)
Or have I missed something? :)
Would it be preferable to have a column on the input table of
"cardinput.inputtype" which could override "capturecard.cardtype"where
necessary? This would allow the bttv daughterboard to be treated as an
extra input on the existing card, which more closely reflects real-life,
and would keep the scheduler happy with no changes.
A more elegant solution might be to completely relocate the input-type
column completely - This involves a much larger overhaul of course.
Again, I hope I haven't missed something obvious...

Steve
