You live in a PAL country and your card can not automatically be detected 2. You want to watch four channels while your card has only one 878 Solutions: 1. As the subsystem ID is zero, you have to manually specify the card number. When card is UNKNOWN/GENERIC, the driver does not program the PLL. Usually cards are manufactured with a NTSC quartz, so programming the PLL is necessary for PAL. Otherwise one gets a "very distored picture". Try loading the bttv module with pll=28 . If you don't have a svhs input, you may want to additionally set svhs=-1 to get color on the third input. 2. There is no solution. The chip can capture only one input at a time. If you switch inputs fast enough, you can achieve something below 6 frames per second. Your Windows application may have some clever logic to switch inputs as soon as possible and in the optimal order. Using only one field of a frame makes this significantly easier.
