audio sync problems w/content from NGC HD channel from TiVo HD

From my earlier post at http://forum.doom9.org/showthread.ph...26#post1374626, thanks to Atak for solving my judder problems on one show. There are still unsolved judder problems w/the White House Revealed ep but I'll tackle that later. (I'm on Ripbot264 v1.15.0.)

I'm still using the same workflow (kmttg to transfer shows from Tivo HD to my PC, resulting in decrypted .mpg files) and I'm now trying to archive some 720p content recorded from NGC HD channel, specifically http://channel.nationalgeographic.co.../4541/Overview and http://channel.nationalgeographic.co.../4904/Overview.

I'm again using [HIGH 4.0] profile, 2-pass encoding and locking size to 2230 MB, and selected X.X COPY stream and creating AVCHDs that I burn w/ImgBurn to play on my PS3.

The video looks fine and there's no judder and audio sync seems fine at the beginning. However, if I skip say 20 minutes into the show, there are SERIOUS audio sync problems. It's off by at least 10 seconds at that point and it happens w/both shows.

Now what?

The (1080i) content where Atak solved my problem with was a Star Trek: Enterprise ep recorded from HDNet. It has no commercials and the resulting AVCHD has perfect audio sync, even at the end. They fade out to what would be a break (when it airs elsewhere) and fade in again w/the next act.

The NGC content DOES have commercials. Could there be audio glitches/changeovers during the commercials causing probs?

Does RipBot264 only use the tools that are in its Tools directory or could I be running into DLL hell? The only significant things that I've installed on this machine (running Vista Home Premium) after "installing" Ripbot264 are T2Sami and multiAVCHD.

(I did also add subtitles via .srt files from t2sami and doubt they're causing problems but haven't re-transcoded w/o them yet, as a test.)
