Audio not in sync with video

I'm using DVD Architect Pro 6.0 (Build 257) on a Windows 7 machine. I captured an HD video and used Vegas Pro 12.0 (Build 394) to edit. I then rendered the video file as an m2v file, and rendered the audio as an ac3 file first, then a wav file. Everything is in sync in Vegas, but when I open DVD Architect and add the video file, the audio starts in sync, but seems to be slower than the video. It doesn't sound slower, but after 3-5 minutes you can see the audio lagging behind the video by a second or 2. Doesn't matter which audio file I use, I get the same results with both files. Suggesions?

It says it is 5 hour length. Is it that long?

Yes it is. I combined it with another video, then edited them down to just under 2 hours total. Comes out to 23 GB and fits on a blluray just fine. I put this file into Windows Movie Maker and saved it as a DV movie. Here is the mediainfo for the MM file. Did the sound forge, or movie maker help, according to the mediainfo?

I'm late to the party--but I'll offer my 2 cents. I would experiment with a 5 minute file, since your lipsync issue occurs before 5 min. I would use Handbrake (https://handbrake.fr/ VERY easy and simple to use btw) and convert your original file to an MP4, and change the bit & frame rates to something universal. If you are going to burn a BluRay, I would recommend you convert the original to 720P x 60 (or 50) which will allow you to burn at a higher frame rate. I doubt you would find a difference in a video bit rate of 25mb/s and 15 to 18mb/s--so use the lower one and save time and files size.

There is a thread of mine a bit further down--- created 1/24/17 discussing my problems with, and MY solution to HDMI captured video from my DVR. Maybe it might help--my problem was video and not lipsyncing. David offered some advice and using Handbrake allowed me to fix the judder or stutter or whatever it's called today :) hth

Thank you rondi! I will check out the thread you mentioned, sounds exactly like the same problem I'm having.
