Ignore what I said then... I saw the "6 AVI files" but missed the auto part.
That the files being written out by VirtualDub aren't syncing properly under DirectShow is a bit of a worry, however, as DirectShow is basically the "gold standard" for OpenDML compliance. Does this happen only with compressed files, or does an uncompressed or nearly-uncompressed file do it too (like Huffyuv+PCM)?

well, I recorded these 6 files with AVI_IO ...... (didnt think it was too important since the resulting files are perfectly in sync IN Vdub, until they leave Vdub)
YUY2 -> huffyuv is what I did through AVI_IO
earlier, i let vdub load and append all six files, and did not do any editing. There is a loss of sync in playback in WMP, but if im correct, this is due to the dshow desync?
So, again, I have one big file, only this time im going to try and encode it without any editting, and see if its in sync. The audio time length and the video time length were shown exactly the same (in dr. divx), so i got my fingers crossed. I got a gut feeling editing before combining the 6 files may have caused the problem?
(P.S. Not sure if it matters, but when I load the 6 files in vdub, and either press the "input playback" or "output playback" buttons, the audio is in sync perfectly......)
I imagine most would suggest to not even make the combined segmented files into one big file, and then encode. Perhaps it'd be best to load the 6 files in vdub, and encode directly to divx/xvid with no editing? Seems more logical. |

alright, latest update......
ive always used 1.4.10, even though i have 1.5.10 on here, I just never saw a reason to change, until now.....
I simply direct streamed in 1.5.10, and it works fine now....... |

those were ffvfw-mpeg4 segments (pcm sound), and i can't say if i used 1.4.10 or 1.5.10 to do the 'dsc'.
i don't remember.
there was never a need to merge mjpeg segments, as avs loads that without issues (unlike ffvfw segmented files...you know why etc.) so i didn't tried that.
the ffvfw merged segments acted normally if loaded to vdub, and went bonkers on dshow; i think offset was more than 30sec (!).
but, as said, i didn't care, as i don't encode video via dshow (and thanks to almighty for that!  )
but it seems as if 1.5.10 fixed it for capuser, so i guess these two write opendml headers in a different way, no?
or perhaps my files were weird because video was heavilly compressed, and sound wasn't, so some interleaving/playback issue occured?
you tell me.

I dont really know why it was acting funky in 1.4.10.
Everything works great now.
Only problem now is, when I encoded to xvid in vdub, the video encoded but not the audio. I took the audio out, encoded it myself, then put it back in with vdubmod.
I had set full processing mode on audio, am I supposed to do something else?  |

yes, pick a codec, just like you did for video; usually mp3 audio compression is used.

thsi means you don't have a proper mp3 codec installed.
