No audio when I convert a Real Media .avi to MPEG???

I have an .avi. It plays fine in Windows Media Player 10(it has video and audio.)

I can't make a .wav file with VirtualDub(it give me an error). It won't load it. It says, "Cannot detect file type of E:\.....xxxxxx.xxxx.Playnow.avi".

I did convert the .avi to an MPEG file with TMPGE and tried to burn it. I got the video, but, no audio. So I played the MPEG in WMP and found I also do not have audio. What do you think??

I opened the .avi in Gspot and it did indeed open. The only info the program is giving me is that the avi is a real media file. The video and audio codecs all say, "n.a.". Here is some additional info:

Size: 430 MB
Stat: File is RealMedia(.RM)

Stream Type and A/V Interleave:

Type: application/vnd.rn-realmedia IMRR: n.a.


Under DirectShow Render:
(I hit the "Render button and it says)

Video Src Type: 4cc: RV40 Audio Src: 4cc: COOK

Video path: (S) --> RealMedia Splitter --> RealVideo Decoder --> (R)
Audio path: (S) --> RealMedia Splitter --> RealAudio Decoder --> AC3Filter --> (R)

Status: Rendering Successful. (click for details...)

Any of this info helpful?? Can I convert the .rm to a .wmp?? Would this fix the audio?

Thanks,
