Encoding Help

I've been looking all around doom9 and videohelp to find a solution to a problem I am having encoding my capture of the DC LDs, but haven't been able to find a solution for a few hours and I'm at my wits end/desperate. I figured that somebody here has run into and overcome the problem I am having and can either point me it the right direction or give me a link to one of the other sites that would be helpful.

I captured each side of the LDs as uncompessed AVI files (approx. 30-35 GB each) without any problems and my encoding is going well using TMPGEnc v2.524 with just one catch that is most noticeable during the opening crawl; it just isn't smooth and contains too much line crawl. Below are the non-grayed out settings that I am using with TMPGEnc:

Video Tab:
Aspect Ratio: 16:9
Frame Rate: 23.976 fps
Rate Control Mode: CBR
Bitrate: 8000
Encode Mode: 3:2 pulldown when playback
DC Component Precision: 10 bits
Motion Search Precision: highest quality

Advanced Tab:
Checked:
Source Range
Inverse Telecine
Ghost Reduction
Noise Reduction (set to defualt and high quality)
Sharpen Edge
Clip Frame

I really appreciate any help.

I'd try unchecking inverse telecine, disabling 3:2 pulldown on playback, and rendering out the crawl at 29.97fps, and see if you still have the same problem. If not, then it's probably due to being incorrectly inverse telecined. I don't know how (or if it is at all) intelligent the TMGPEnc inverse telecine is - does it compare frames or fields to work out which one to drop, or does it just drop every fifth one regardless?

How about a screenshot to let us know what you mean my line crawl, and maybe we can help.
I'd do an IVTC pass and a cleanup before encoding back to dvd anyhow.

I actually figured it out earlier today, and it was an error in the inverse telecine process, things look good now. I also changed the bit rate to 2-Pass VBR, DVD Architect had issues with CBR and wanted to recompress anything done with a constant bit rate. Thanks guys.
