What's "field sync"?
"The insertion points of the field sync (once every 312 MPEG packets)"
Ack, I don't think it can do that.
That would require a DVI input IMHO.

Yes. IMHO "native" PAL is "768x576" resized to 525 lines.

I think it can do that.
I have such a box somewhere "flying" arround (and can't find it.
Maybe someone "lent" it...)

I know that the devices have a dedicated chip wiht many many pins
I noted the type somewhere...

You need an image RAM...that's on the analog VGA card.
I don't think that the box has storage for more than 2..4 scan lines.

That can the box do.
The image was OK. I used the box when the VDR box(hardware)
did not run...
Instead of carring a heavy VGA-Monitor to the living room, i simply
connected that tiny little box to the TV and the VGA-card.
If there would be only the odd lines i'm sure i would have noticed
that 25Hz flickering and lost of resolution in the BIOS-Screen.
