Ha, look at this:
This really makes me upset. I also bought US version of Sliders. And with this simple .AVS:
LoadPlugin("DGDecode.dll")
LoadPlugin("Decomb.dll")
MPEG2Source("1.d2v")
Telecide()
it gives great quality. Seems the PAL version was made by some idiot who didn't care, didn't know enough.
And here's the NTSC clip:

It's from a 6-disc season 1&2 combined release:
