fixing DVD audio tracks / reauthoring videos

[RetroDude83]

Hi, I'm new to dvd editing. I've received some DVDs which only have one audio channel, meaning they are true mono, it's either the left or right channel missing. is there a way to copy the one channel that has the sound to the other channel? What software would I need and is there any free software that is capable to do it?

also I do have some short videos in VOB format which I would like to put onto one dvd because I see no point burning a 5min performance onto one disc, while the disc has way more space for more stuff. is there a free dvd author tool, with simple user interface that can do this? like creating a Video_ts folder, containing multimple vobs, with a simple menu?

thanks for reading!

You can extract the audio (demux) and use something like audacity (http://audacity.sourceforge.net/?lang=nl) (freeware) to make two channels. It will still be mono, but 2-channel instead of one.

There are a lot of different authors around ranging from free to expensive. Have a look here: http://www.videohelp.com/tools/sections/authoring-dvd and take your pick, Nero will author as well.

dvd audio extractor also work then just re create the 2nd channel with a copy and paste

Thanks for the hint on audacity, I got it all sorted now. demuxed the audio, downloaded an ac3 plugin for audacity to make the fake stereo, reauthored the stuff in TMPGEncDVDAuthor including the new audio track.
