I've tried allmost all settings on that, and the best was a reasonable
quality. Is there a sort off ideal setting for the Nvidia with PAL? The
examples on the mailinglist seem to be tailord for NTSC.

For example, the colors looked 'overdone' the bright colors where very
bright and the dimm colors all looked grayish (i hope you understand).
Also it looked a bit unsharp. But i've seen the same with the ATI if I
enable the deinterlacing options. But I can switch that off with the ati
without a visible impact (only the picture looks sharper).
