We'll want to fix this problem.  Its means the system is too busy to
accept data and it was thrown away.  Not good for digital compressed
streams.

I believe the problem is that the i2c interface is exposed to the rest
of the kernel and with multiple cards there is a conflict.  If this
isn't right please correct me.

I guess we'll have to look at how the other tuners interact with the
bttv driver because they must communicate with the i2c interface as
well.

Thanks
