About edge halos: they are present on ALL the laserdisc captures of JP I've done, both copies of PAL IT, in PAL UK and in NTSC DTS... I thought about a Pioneer laserdisc player fault, so I capture some footage using a Philips player... they are still there!

I picked up the SW captures (I have done A LOT of them), and magnifing 8x random frames, it seems there are not edge halos...

Again, in JP those halos could be seen only on the right side of dark objects over bright background (like trees over the sky), and are quite visible in only few scenes (obviously, if seen frame-by-frame, and magnified, they are more visible...)

At the end, the causes could be:

my capture card is guilty (comb filter problems? but for JP captures done using the Philips laserdisc player I used composite, while with the Pioneer I used S-Video...)
laserdisc format is prone to edge halos (but there are none on SW captures, either done with laserdisc and VHS)
Jurassic Park master used for the laserdiscs has problems

To be sure #3 is wrong, someone else should capture some scene - the best should be the first encounter of Alan and Ellie with the brachiosaurus; the edge halos could be seen easily on the trees on the right... if there are NOT edge halos, it should NOT be the master or the laserdisc format itself, but only my capture card... but why with JP and not SW?
