AC3 Channels

[alchemist]

I am trying to assemble a DVD using TMPGenc DVD Author. I am using files that were encoded from DivX to MPEG format after extracting the AC3 streams with VirtualDub.

My problem is that some of the AC3 streams are 3-channel and others are 4 channel and TMPGenc DVD Author requires all the files on a track to be consistent.

Is there a way I can strip the extra channels from the AC3 files with 4 chanels or possibly add a blank 4th channel to the 3-chanel files so I can put them all on one DVD?

You could try GoldWave for this - I know that it supports AC3 and is described as a "semi-pro" editor. Give it a shot and see how it works.

Good luck,

The other way is to put them on seperate tracks. Saves messing with the audio.

I've tried using GoldWave but every time I try to open an AC3 file with it, it crashes with an error about neroadb.dll. I've tried uninstalling and re-installing several times and can't seem to fix the problem.

In the meantime, I have used the AC3Machine front-end for BeSweet to downmix the LFE channel into the Left and Right channels for my 4-channel files so they are left with 3 channels. (L+R+C). I'm about to make my first disk with the downmixed files so I'll report back with the results.
