I don't think its necessary to capture the mono track because None of the Jurassic Park films were designed to be heard in mono. JP, as I heard was released in 5 channel Dolby and 6 channel DTS, was it not? The Lost World was also released in Dolby SR prints and DTS prints.

The clip is much better, but you have to De-Interlace it. When the T-Rex stops near the edge of the city and roars, do a step forwarding (frame by frame), you'll notice the NTSC interlaced lines (around the jaws of the Rex) . Now they are still visible after I applied the de-interlace filter in VLC, that means you have to create a solid de-interlacing script in Avisynth and Virtualdub. The de-interlace script has to be strong and effective so the interlace lines aren't visible. Because every time there is movement, these interlaced lines will be distracting to watch.

Let me know!

And thanks for that designation. Glad to have helped!
