I am trying encode I am Legend Blu-ray to my media center. I've searched around but didn't find this exact issue. Using the following process:

1. AnyDVD HD to rip (BD-R has the latest firmware)
2. AVS file pointing to rip, looks like this:

DirectShowSource("D:\Convert\Legend\I_AM_LEGEND_NA\BDMV\STREAM\00000.m2ts",audio=false)

3. Virtualdub to open the AVS and convert it to XviD
4. xport to demux first track (which is DD5.1, straight ac3)
- have also tried demuxing the second track (TrueHD), then ac3to to convert but get the same result.
5. VirtualDubMOD to mux it all back together.

The audio goes out of sync at the beginning of the movie by about -0.6 seconds, but by the end of the movie it's off by about -4 seconds.

I've tried several different settings in VdubMod, shorter interleave, etc...

Any thoughts on how to get the audio in sync?

**** EDIT
I was able to resolve the issue. For some reason my DirectShowSource filter was loading ffdshow. The video is 1:40:31 long, but somehow ffdshow was shrinking the video into 1:39:05, then there was a little over a minute of black screen. Once I got ffdshow out of the equasion for encoding it was fine. The video took up the entire 1:40:31 and the audio synced no problem.

@Atak_Snajpera - I really appriciate your reply.

Are you suggesting this becuase you had the same issue?

Also, I'm unable to get DGAVCIndex to get read any of the PIDs correctly. I tried both a .ts and the Legend m2ts. Best case it just hangs.

Any other thoughts, anyone have this issue?

use DGAVCDEC

I think 'I am Legend' is VC-1(according the the bluray.com reviews), so dgavcdec wouldn't work.
