I am occasionally having audio sync playback issues with AVIs created by AGK. Using original DVDs as source, I create Xvid AVIs using AGK and copy these AVIs onto an external HD that I hookup to my HD set top.
I use no compression in DVD Shrink (only stripping out menus/trailers/extras) and select 100% quality in AGK when creating the AVIs (using the main IFO as the source). What could be a potential source of the cause?
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Yep, do a movie only decrypt using DVDFab HD Decrypter. Following that up by running the VOBs through FixVTS is a good idea as well.

If doing a movie you should be using DVDFab HD Decrypter in Main Movie Mode or whatever it's called. There's never any need to put the entire DVD onto the hard drive when all you want is to convert the movie to AVI. Perhaps there are referenced PGCs/Titles, short ones without any associated audio that play before the movie begins (a split second or more of black frames) which might throw off the audio for the movie itself. That being said though, it's often easier to just fix the delay rather than spending time encoding and reencoding. It's very easy to do. In Baldrick's guide he explains how to find the delay:
https://forum.videohelp.com/topic374348.html
That guide is for fixing DVDs, though. Then to fix it for AVIs you open the AVI in VDubMod, set Video to Direct Stream Copy, go into Streams->Stream List->right-click the audio->Interleaving, and then fill in the amount of the delay in the Audio Skew Correction box. OK back to the main screen and then File->Save As (give it a new name), -

I pressed the + and - keys and saw no effect. I did not see the "audio delay" indication that he posted with the first illustration in Baldrick's guide. -
He's using Media Player Classic Home Cinema. I've never seen it in the blue box in the upper left hand corner, though. I figured that was a just newer version than what I have. I see it in the lower left corner, as in his pic. I know I never adjusted anything to make it work, so it must work by default. You may not be able to tell any difference unless you make it over 100ms or so. It advances in increments of +/- 10ms.

OK, try this. Play something using it and pause it (click on the screen). Then right-click on the screen and go Options->Internal Filters->Audio Switcher. Check and see if "Enable Built In Audio Switcher Filter" is checked. If not, check that box and hit "Apply" followed by "OK". Close out the player and then restart it. Then see if the +/- keys work to show the Audio Delay in the lower left of the player.

Ok, i was having problems figuring this out.... here is what i discovered.
1. Open one of the VOB files using Media Player Classic Home Cinema (MPC) and pause the video.
2. Goto File->Properties
3. Click on the MediaInfo tab, scroll down to Delay Relative to Video, which in this case is -68ms (milli-seconds)
Hope that helped someone out... it was driving me nuts ! -
I've been trimming movies the way you do for a few years and figured out the problem was with DVDShrink. The author went to work for Ahead and renamed it to Recode. The problem with trimming appears to have been fixed since the version that came with Nero 7.
Another way around it is do as Manono suggested to extract the Main Movie only with DVDfab HD Decrypter, run it through AutoGK, then trim the AVI with Vdub set to Direct Stream Copy. Minor issue here is you're limited to cutting to Keyframes, even if you set the start mark to another frame it will cut at the next keyframe.
