Changes: (1) several card-specific tweaks. (2) make software vs. hardware i2c configurable per TV card. (3) reinitialize image parameters after chip reset. (4) make bttv quite by default on frame drops. (5) new insmod option: "debug_latency=1" to enable frame drop debug messages. bttv is quite sensitive to irq latencies, especially when capturing both video and vbi. There are several reports about problems due to this, I don't see that on my machines through. (5) dumps a stracktrace if the driver thinks the frame drop is is caused by high latencies as experiment, lets see whenever that helps ...
