Antcu,

Since your source was a DVD player, it's output luma phase must have jumped 180 degrees between captures (a bit like pal).

Won't help you with LD captures, since the phase is already baked in.

I am surprised it canceled out so neatly. If you can get the same trick to work with a laserdisc capture - i'd be extremely surprised.

Some background before I ask my question: The Panasonic LX-900 runs the video signal through its own internal comb filter before recombining it for the composite out (i.e., the composite output is not "pure"). The simple 2D comb filter it uses is non-destructive, so it doesn't harm diagonal resolution like 2D adaptive ones do.

Since the LX-900's internal comb filter is non-destructive, I can recombine the signal outside of the player before passing it to a better comb filter. (This is what's currently being done, except I'd be doing it outside of the LX-900 rather than inside.)

What if I use my Panasonic DMR-ES10 to recombine the s-video signal? It non-destructively digitizes the input signal internally for its frame-sync/line-TBC to work, so wouldn't the DAC used to convert it back to analog change phase like my DVD player does?
