Adding A Second Audio Track To A DVD

[tooonami]

Hi, so I had a .MKV file which I fed into ConvertXtoDVD and then burned it to a blank media, the resulting dvd had no audio when played back in a standalond DVD player.

My question is, is there a way to add a second audio track to an already authored DVD folder? I have already fixed the audio and merged it back into the .MKV file, but, I wanted to know if there is a way to do the same with a DVD folder so I don't have to convert the .MKV files again.

Thanks.

Yep, demux the video from the dvd with pgcdemux, convert the audio to ac3, add the old video and the ac3 file to the authoring application like muxman or guifordvdauthor.
