Ok, fairly complicated to explain, but I bet there is a fairly easy way to solve this problem.

Let's say I rip chapters 2-7, cutting off chapters 1, 8, and 9. I use stream selection and I only rip the video track and the 2ch English audio track.

So then I have a VOB that contains the video track (I assume this is mpeg2?) and an AC3 audio track.

I load this up into Virtual Dub Mod and I demux the audio out. So now I have the AC3 audio track seperate. I then use BeSweet and BeLight and load that AC3 file up. I set it to automatic delay based on the information from the AC3 file. Then I output to a 128 Constant Bitrate, 44,100Hz sampling rate, Mp3 file.

Then I use Virtual Dub Mod again and I output the VOB file to a 362 by 272 resolution Xvid AVI.

Ok, so now I have an Xvid AVI file and an Mp3 file.

So, what I am actually doing here is muxing these two files together in a format called PMP. For those of you who don't know what this is, it's a custom PSP (Playstation Portable) format that allows you run full resolution videos on your PSP (PSP's normal video's resolution is crippled to a much smaller size). The stipulations of PMP is that the video needs to be Xvid and either resolution 480 by 272 for 16:9 or 362 by 272 for 4:3. The audio needs to be Mp3 at 44,100Hz sampling rate.

So with all of that in mind, here is my problem. When I mux my Xvid AVI and Mp3 file into the PMP format, the audio is out of sync. The audio is also out of sync if I mux the two into another format, like AVI. The audio gradually gets more out of sync as the video goes on.

My guess is that the Xvid AVI file and the Mp3 file are different lengths and causes sync problems. However, I have no clue how to fix this. I'm sure there is a very simple answer, but I have not been able to find it anywhere.

I have been using AutoGK in the meantime for all of my 16:9 videos, but since AutoGK cannot encode into 362 by 272 resolution, my 4:3 videos are out of luck.

Thanks for reading and thanks for ANY help!
