I am trying to put 4 ProVideo PV-150's in 1 machine. They cards are recognized, and they are their, but in order to get bttv to work with them, I need to modify BTTV_MAX in bttvp.h. I tried both 0.7.x and 0.9.10, but under both drivers, when I set BTTV_MAX to more than 15 the module freezes the machine. If I set it to 15, I can access all 4 cards, except 1 port on the last card. Do you know of any reason why a setting of 16+ on BTTV_MAX would not work? Any modifications to arrays, etc. I could manually make? Thank you, Ryan
