Proof of Life is driving me insane

[kbaugh]

I'm copying Proof of Life to a DVD-R. It's larger than a DVD-5 so I need to remux it down. Here's my process:

-Rip DVD (SmartRipper)
-Strip out the extra audio tracks so I only have English 5.1, English sub-titles (IFOedit)
-Remux the videostream to a lower bitrate, rejoin the altered videostream into the VOB's (ReMPEG2 to alter bitrate, IFOedit to rejoin) In the case of Proof of Life I'm using 72% as my scalefactor, based on my calculations, I've used lower and gotten significantly higher quality previously so that's not it.
-Set VTS Sectors for final burn (IFOedit)
-Burn with PrimoDVD

I've done this successfully with plenty of DVD's. However when I lower the bitrate with ReMPEG2 on Proof of Life the video shimmers. It alternates between 2 frames of horrible (sub-VCD) quality and one frame of near-DVD quality.

All my other copies I've created using this process just look like that final near-DVD-quality frame. Anybody out there know why the video would be making this 'shimmer' effect? It starts after the Warner Bros. first logo and doesn't stop from there on out.

I've tried it 3 times and it keeps doing it . . . any suggestions?

By any chance does the movie have angles in it?

I burned a couple of coasters now that the movies had angles in them. I didn't get jitters, the player just locked after a few seconds. I found a sure way around this problem, but I don't know what the root problem was. I've used this method now on about 20 movies and it hasn't failed me yet. These movies are all over 4.7g after stripping down with ifo edit.

Rip entire movie with dvd decryptor
frame serve the main movie vobs using DVD2avi to tmpgenc to encode.
remuxing the audio .ac3 and m2v
create new vobs and ifo's and burn.

I think it has something to do with the angles. As soon as you get past the studio trademark all :devil: breaks loose.
