I must say that - my PAL DVD's of Farscape and LEXX that I had looked WAY, WAY BETTER then my R1 NTSC versions of Farscape.
BUT, I have seen NTSC stuff converted to PAL and I think they look a bit stretched height wise and the PAL to NTSC stuff will look blurred or fuzzy and will sometimes show scan lines (sometimes even when deinterlaced during conversion) - that's what I've noticed anyway...
BH - your stuff looks GREAT!!!!
