    I did the Full TMPGEnc process, everything from AVI-MPEG Conversion, to the DVD-Auhtoring. And for some reason or other, on my Main DVD player of the house, it doesn't playback the sound, only the Video. I hit the Audio Button on my remote, and it recognizes it, however that doesn't matter. The DVD works perfect on EVERY other DVD player I've tried it on. Is there some way to possibly switch the audio type using TMPGEnc? Or is it possible to have Two Audio Sources on the Same DVD? Like professional DVDs?

    Under NTSC DVD specs you can't have mp2 audio as the only audio stream. Therefor if it is an NTSC player, it doesn't have to play the audio.

    TMPGEnc DVD Author from recollection only supports one audio stream. That can be AC3 though, then it should play on everything.

    For something quick and easy, you could convert your source audio to AC3 with ffmpeg.

    So basically, in order to burn the DVD, I needed to removed the AC3 to get it to synch properly. And now I can convert it back?

    Well, I solved my own problem. For those have run into this problem, here is an easier solution than the one in my response. Although you can Re-Encode into Dolby AC3 using various tools and utilities, and easier way, using TMPGEnc, you can actually choose between Mpeg-II Audio, and Linear PCM Audio, which is uncompressed audio. This solved my problem with the DVD-Player playback. Thanks a bunch, and hope this helps someone else.

    LPCM often isn't practical due to the size. You really can't get much easier than ffmpegGUI for audio encoding anyway. Accepts mp2, avi, mpg, vob, etc. as input. Also there is the TMPGEnc AC3 plugin which will let TMPGEnc DVD Author re-encode the audio to AC3.

    I have the plug-in, however I can't get it to work for some reason or other. And ffmpeg is for MacOS no? How do I re-encode using the DVD-Authoring part of TMPGEnc?

    The plugin doesn't work for regular TMPGEnc. Just DVD Author and Xpress.
    For TDA you just change it to AC3 and it converts.

    ffmpeg is cross platform, it was originally written for linux, but works under windows and OSX. ffmpegGUI is windows only.

    So if Im using TMPGEnc Express 3.0, what would I have to do during the conversion process to encode in AC3? I have the AC3 Plugin, however only Linear PCM, and Mpeg-II Audio is available. I installed the TMPGEnc AC3 Plugin, but I don't see it!

    Would I need to extract the AC3 first? Even though I still have the plugin installed, for some reason or other the audio is still not synching properly, so I extract the AC3 Audio, and convert it. However should I use the raw Ac3 File as an audio choice?

    Back track a second. Your original audio is AC3? No point in converting it then, just reuse it. That is unless say you want 2 channel and only have 5.1.

    As for the AC3 plugin, either it is too old or not installed/registered properly.
