Thanks for the hints. Unfortunately the cards in question really are fairly generic and thus don't appear in the list. I tried the first 75 cards as insmod options (using a script of course), and some of them are different, but none work properly.
I am lucky in that I still have a spare. If you could suggest a very well tested kernel for bttv (2.6.9?), I can set up another machine with that kernel and the remaining card. That should allow me to isolate the problem better. At the very least I could get the right card= option to use for the broken pair. Hopefully I will be able to generate a table entry for this card for bttv-cards.c; I'll look some more at this tomorrow.
I've heard that there is some way to dump eeproms; Is there a way to write them also? If I could copy the eeprom from the unused cards to the (now broken) pair that might fix things.
Thanks, Jim
