TMPGEnc doesn't find sound for AVI file.

[1000watts]

I've found a program GSPOT 2.0 to find out what kind of AVI file I have. The Program tells me that the AVI file is a DIV3 video file with AC3 audio format. It also tells me that GSPOT wasn't able to find an audio code which will decompress this format.
I've loaded NEMO code pack and installed the AC3 audio decoder. This still hasn't helped.
I've also loaded TooLame as an external audio encoder in tempgenc, but that hasn't helped either.
When I play the file in windows media player, it sounds and looks fine.
Any suggestions on how to get the audio portion of the AVI recognized so I can convert the AVI to MPG for a VCD burn?
My running the conversion on an Windows XP system, 512M & AMD 1800.
Any help would be appreciated.
Thanks,
1000Watts.

The easiest way is:-

Open the file in VirtualDub, then ensure Video is a direct stream copy, audio is full processing and select no compression for the audio. Then save the AVI as something else. This file will be much larger, but will import into TMPGenc OK, with Video & Audio.

Not that I want to stomp all over Ratware 's post but he made one incorrect statement about the audio. VirtualDub cannot handle ac3 audio streams other than doing a direct stream copy. Load up the avi as before, select direct stream copy for the audio. Then go to the file tab and select "save wave", select a file name and add .ac3 as the file extention. Then save as "all files". After this you're going to need an external encoder such as BeSweet GUI: http://dspguru.doom9.net/ or HeadAC3he: http://mitglied.lycos.de/darkav/svcdguide/svcd.html to convert the ac3 file to wave. Then use this as the audio source for TMPGEnc.

GSpot should correctly idently AC3 streams. It will not, however, identify OGG audio, which is probably what you have.

If you re-read the original post it did correctly identify the codec in question. Since ac3 is decoded thru Windows Direct Show using the filter provided by the Nimo codec pack there is no decompression codec per se.

Your right. I skipped right over that. You can also just enclose your saved file in quotes "" to ensure it doesn't add the default .txt extension.
