Interesting. OK.

Don't I know it. I ask because my experience so far has been that, on many
cards where TV-out was not the main attraction, it was often poorly done
to the point where it was practically impossible to adjust it at all, or
at least, well enough even for _most_ televisions. Add linux to the mix,
where tv-out support is often more dubious, and then I'm really afraid.

Doesn't have to be perfect. As long as I can get the picture centered and
not stare at black bars I'm happy.

You are a gentleman and a scholar.  :)
