I noticed some problem whenI try to convert some wmv clips into one DVD. When I load the wmv file in the 1st Input step, I noticed that the Audio field says "AudioSteam 1 wma 0ch", and that's the only choice int he audio stream. I continued the conversion still.

The conversion went through, and log file says everything is a sucess. But when I mount the dvd_image, and play, there is no audio. So I went to the working folder, and found out that, for a 30 min wmv clip, the converted ac3 file is only 242 kb in size. Very tiny compare to the usual size of AVI file's audio ac3 encoded file.

I tried with some other wmv file and the tiny ac3 file is always there. I think it has something to do with the demux program avi2dvd uses, but not too sure. Is there a program to analysis wmv files like G Spot to avi files? I would like to check the audio part of my wmv files. They played alright on their own.

Thanks for any help.

Ok, I tried some more with wmv files. I think the demux program avi2dvd uses simply does not like wmv file. So there is nothing for BeSweet to encode, resulting in tiny ac3 file produced.

However, I looked around, and found some inspirations from a article on videohelp.com, about opening rm files with AviSynth and VirtualDubMod. So i simply wrote a avs file with one line:
DirectShowSource("C:\test.wmv")

Then use VDMod to open the the avs file. It works, the file information in VDMod indicates that the audio stream of test.wmv is PCM uncompressed. I wonder if that is causing the demux problem in avi2dvd.

Anyway, I used VDMod to get the audio, to match with the m2v file created by avi2dvd. Then use DVD Author to author the dvd. I thought it wuld be helpful to anyone who is having similar problems.
