The notch filter truly is horrible. It limits resolution to

reason not to use bttv-based cards for a mythbox. I do find it good
comic relief to hear of people having CPU performance problems
capturing 720x480 MPEG4 from a bt878 card, though... :)

There's a very good reason to do it if you're using pure digital (SDI or
PDI) inputs. No scaling is always better :)
I'm still wondering if it's possible to hack a PDI input onto the
PVR-150, by tri-stating (or in the worst case pulling) the cx25480 and
taking over the video lines. But I don't have a spare '150 I can hack :(
Does anyone know if the internal video is BT656, or if it's reliant on
frame / line starts on other pins than D1-8, Clock?
Cheers,
Allan.
