what stuff?
Do you mean when you don't run myth?

there are none.
You can't control it like that - yet?

Yes
It was discussed on the ivtv list recently.
There may be a way to reduce the fb size and apply offset so it appears
to X to be maybe 680x430 offset by +25+25 - but you can do that in myth
anyway.
No real resolution to overscan yet.
Others are interested - it depends whether we can find out what to tell
the saa7127 video output chip :)
