I think it is a bug in the ivtv-0.4 tda9887. I've made some fixes to
that module in ivtv-0.4. See if that helps.

That's really interesting. I always wondered who would need that
high-deviation stuff :-)
You mention that it did work in an older ivtv version. Do you know what
the last working ivtv version was? I'd like to compare that one with
the current cx25840 module.
Thanks!
