MPEG2 encoding if interlaced vs progressive - this is a great thread on uk.tech.broadcast (link in RH bar) concerning qualatative differences between encoding 25i and 25p material - it seems that DCT based compression deals better with non-interlaced material (not really a suprise - there is no motion within each frame!) - I still can't get away from the fact that I love the look of proper interlaced video!
