You have found quite a strange bug... It looks like the tda9887 module
didn't load, and bttv got the tda9887 mixed up with the tua6034... I
have no idea why or how this could have happened. I have a patch that
might fix this for you, but I don't think it should go into cvs. Try
this out and tell me what happens... (for curiosity's sake)

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this should be a tda9887
> tuner 0-0061: chip found @ 0xc2 (bt878 #0 [sw])
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this is the tua6034
what went wrong?

The following patch should force bttv to probe the correct tuner at 0xc2
... It looks like the real problem here is in tda9887, but I'm baffled
as to how/why.
Apply this to v4l-kernel cvs
