Which came with my card, but what I'm saying is if there can only be a total of 2 composite inputs addressable by each "pvr-150" card, then the driver should only list Composite 0/1 for each device, not 0, 1, 2, 3. Actually, I don't think you can address the other "cards" input devices. So being able to enumerate all of the combined inputs is kindof useless and pretty confusing. I'm going to have to do some experimenting to see what exactly happens when pulling from the different Composite inputs, now that I know that the card is working properly. Hopefully I'll have time to do the testing and put together a table of what does what in the next couple of days. - -- James A.
