I have Windows 7 x64 and use TMPGEnc Authoring Works to burn my DVD's. I just found out that any AVI encoded with AC-3 for audio results in choppy audio when burned in TMPGEnc and played back. I have the AC-3 filter installed but I don't know much about configuring it, or if there's something I need to enable. I should mention that without the AC-3 filter installed you get no sound during playback for AC-3 encoded files. I'm also wondering maybe I should convert the file's audio to mp3 audio using AVIdemux or something. by the way ConvertXtoDVD burns and plays back the same file just fine.
Codecs do not get involved when writing to the DVD, only when the media files are played. Your post is a little ambiguous; what are you doing in Tmpgenc? Converting AVI to DVD mpeg-2 ? And authoring? Generally, the ac3 that's in the AVI is kept in tact, no conversion is necessary, since ac3 is fully DVD compliant.
Yes I was just burning an AVI to MPEG in TMPGEnc and all I know is, when recording an AVI file that was encoded with AC-3 audio, if I did not have AC-3 installed, I could not hear the sound when the DVD was played back. But for some reason in Windows 7, the latest AC-3 filter that I installed seemed to be resulting in choppy audio burns, so what I did after I posted this last night is uninstall that, then I installed the K-Lite Codec Pack, but I just enabled AC-3 on that and now the burns come out fine. I don't know what the difference is between running the full blown AC-3 with all of it's configurations and just installing it from withing the K-Lite Codec Pack but it worked!
That's good news. As you mentioned, the codec pack includes its own "ac3 filter", so no need to install in separately.
