Hi
Just got back after the Christmas break and took a look at this. The problem with your suggestion is that the frame rate goes down to 25Hz, which the TV will not scan.
I did a little research some time ago and I don't think there's an "official" progressive PAL specification but what I found indicates that the horizontal frequency increases from 15.625kHz to 31.25kHz - ie. it doubles.
The mode I mentioned above does indeed result in a 31.25 horizontal frequency and thus a 50Hz frame rate:
Modeline "1024x576p" 43.500 1024 1128 1232 1392 576 577 580 625 -hsync -vsync
(In case anyone's wondering, I do have a bunch of 720x576p modelines as well but absolutely none of them work, hence the choice of horizontal resolution.)
I tried your interlaced PAL modeline on my TV and it produces a fine picture but I still get my problem with the flashing input identifier. When using the interlaced component output from the DVD player it's not there so I think I've got a problem with the Key Digital converter somewhere, maybe with the sync signal. :(
Is anyone else in PAL land using one of these converters with a Panasonic TV?
