I used to have a problem with a slight, but bloody annoying flicker when capturing an interlace source (576 lines PAL) and encoding to an interlace output SVCD. Usually the field order is bottom field first (B) which is what you bung into Tsunami Enc - this resulted in the slight flicker. Changing this to top field first (A) made it even worse.

Well the solution is to field swap in Vdub AND use top field first in Tsunami. Nice crisp pictures. Bloody BT capture card, it had me pulling my hair out for weeks.

Cheers,
