no audio after using VirtualDub

[nikkoforever]

I used DVDDecrypter to rip a chapter I wanted. When playing back this ripped file using PowerDVD I have audio. I used VirtualDubMod to edit down the chapter to just the scene I wanted and convert it to AVI. It asked me which audio stream I wanted and I selected the appropriate English audio stream. After playing back the completed file, however, there was no audio at all. Any ideas on what might have gone wrong? Thanks in advance.

Did you use Full Processing Mode or Direct Stream Copy for audio? If your answer is the former, what type of compression did you use?

This is the first time I've used VirtualDubMod, so I'll just tell you exactly what I did, and perhaps you can tell me where I went wrong.

1) ripped a chapter using DVDDecrypter
2) opened VOB file using VirtualDubMod (File>Open Video File)
3) selected AC-3 substream 0x80, which according to the info text generated by DVDDecrypter is the English language track
4) used the Mark In and Mark Out buttons to select parts of chapter I didn't need, and then deleted them (Edit>Delete)
5) selected Save As under File to save the clip as an AVI file

That's all I did. I didn't play with any of the settings. I just checked now and it appears that Full Processing Mode is what it defaults to. When I checked under Compression, Uncompressed RGB was highlighted.

Any ideas/tips would be much appreciated. Thanks.

Ok, if I understand your post correctly you didn't actually compress the audio so you should have an AVI with the original AC3 audio stream. That being the case I think you just need the AC3 Filter. Try installing it and play your AVI again.

*sigh* Well, I did that. I played the AVI in Windows Media Player. There is some sort of audio on there, but it is just a blip every now and then. Also, the video seems to be moving slightly too fast, but I can't tell for sure without hearing the corresponding audio. Any other suggestions? Sorry to have so many questions.

I want to make sure that your AVI does in fact have AC3 audio. Right click it and select "Properties", then click on the "Summary" tab. You should get a window that looks like this(if you are using WinXP):


In the area marked red it should say "AC3" or something simillar. If indeed it does than I can only suggest you try playing your file in another media player like Media Player Classic. If these efforts don't yield any results perhaps someone more knowledgable than myself can be of help.

Unfortunately, this is what I see:



Not sure what the trouble is. Thanks for your help. Anyone else have any suggestions?

Try using G-spot. It should tell you the right audio codec you need.
