Hi. The last several kernel versions have led to broken bttv (up to 4 or 5 kernel versions ago, I could watch tv on either mplayer or xawtv), but lately bttv is broken. My card is an 'bt878 compatible built by ATI (ATI TV Wonder VE). I'm pretty certain it worked as late as 2.6.14-git7.

You need to do a git bisect (check the list archives) to isolate the
change that broke it.

OK.  I will, but I will add a tiny bit of additional info first.
dmesg shows bttv loading up like this:

.... I will do the git bisect and reply in a bit.
Thanks for your reply,
Bob
