"Which laserdisk was used for that shot. The uncorrected color looked worse than the THX versions."
For one of these, I think I used my original capture as a comparison. It's been awhile. I'll have to double-check.
"Unfortunately the aspect ratio of the video is off, it seems that the vertical resolution has been compressed when it should have been stretched. (Or was that just so that the before and after could be shown in the splitscreen arrangement?)"
Correct on the last statement. I tried to make both scenes as visible as possible. Many of the "fixes" I've made are very, very tiny, and are lost in the detail due to 1) being reframed to a smaller size, and 2) by virtue of the DivX codec. In the Flyover scene, most of the dropouts on on the planet surface, but you really have to look to see them. I'm probably far more meticulous about them than I need to be (after a first run in Combustion, I review the video in VirtualDub, which makes these glitches stand out even more), but if I can see them, then I delete them.
