DVD -> PSP audio out of sync

[Nafai]

I'm using Yade X to retreive streams from a DVD (multiple audio and subtitle tracks I assume would mess things up if I used a VOB method). Here's my steps:

Drop .m2v file into the well, select PSP from the preset dropdown. Audio tab, Add Audio, and select the 00-en.ac3 (default english audio track). Encode.

The audio starts out fine, and the drift gets gradually worse throughout the movie. I've used this method countless times and never encountered this.

Video In: mpeg-2, 720x480, 9800 kbps, 23.976 fps w/3:2
Audio In: No Audio (added AC3 file via the audio tab)
Video Out: ffmpegx xvid, 368x208, 300kbps, 29.97fps, no crop
Audio Out: aac, 24000Hz, 64kbps

Help! Looooooong trip tomorrow and I'll die of boredom without figuring this out! :P

Went ahead and updated from version "s" to "t", and of course, lost the Add Audio function, and so then tried it from the VOB. The audio is WAY off. Much more like what I'd expect from losing 5 frames every second due to the difference in framerate of NTSC film and PSP NTSC 29.97.

What's the deal here? Why did this work perfect in the past but breaks now?

OMG, why the frakk did this stop working? I've tried a bajillion different ways to rip and encode, and the drift remains. Aaaaarggh!!

FWIW, I'm on 10.4.3 with the latest Quicktime, 0.0.9t ffmpegX. The text portion of the About dialog indicates 0.9t r3, yet the title portion of said dialog reports 0.9t r4. I guess that really doesn't matter since the original problem in my first post was with version "s".

What's at fault? Anyone with similar software versions have a successful DVD -> PSP workflow they can share? I even downloaded PSPWare (shudder) and it was even worse. Audio wasn't even the same length as the movie.

I don't think there has been significant changes, but in desperate cases, you may encode to mencoder DivX first then to PSP.
