On my old CRT TV where I made a S-video input myself (by looking at the
schematics of some slightly newer but similar TVss from the same
manufcaturer (Grundig)) I put in a potentiometer on the chroma signal
so there I can adjust the level freely.

Haven't tried that on the plasma though.

But anyway the CRT shows that the timing is different between the DVD
player and the C128. This is consistent with what I got 15-20 years ago
but with a C64 and a CD32 as sources and both the same CRT TV and a
Commodore CRT monitor as displays.
