Have you got a PAL-spec modeline setup for 720x576? I'd start with
that, get it looking nice, and then think about using higher
resolutions that might cause problems. Other things like having a
suitable DisplaySize for the aspect of the TV and possibly changing
the size of your fonts also apply.

I'm running 1024x576i with deinterlacing with no issues, apart from
some overscan losing the very bottom of the screen. It's definitely
worth persuing as the picture is better IMO than with S-Video and
_nearly_ as good overall as my PVR-350.
