I don't think there is any other video card/device driver combination that does as perfect a job on Linux at properly replicating the properies of television broadcast as DirectFB and the G400 are doing. It's a shame considering the G400 is out of production now and any new cards with TV-Out are just plain undocumented due to the "copyright consortium" tying the hands of the hardware/driver manufacturers. ~sigh~ > (Odd, even, flat, spongy?

Top/bottom it is then. > I don't know why anyone refers > to odd/even fields (except for those video engineers working in their > specific domain where it is well-defined).) Probably where I got it from. Not me being the engineer but from somebody who does work in that domain. > Lucky you, indeed! Well, yes, lucky to a degree, but moreso that it's just the right thing to do to deliver consistent results when the user does not request a preference.

Can also be set by the driver. bttv, I have heard, will only deliver top-field-first. > Luckily for you, lavrec defaults to top-field-first. Indeed.

Right. I agree completely. > DV, on the other hand, is always bottom-field-first.(*) Interesting. b. -- Brian J. Murrell
