After analyzing and processing for 2 days, I am still at a loss although I have made some progress (very little) :confused:. Here is my situation and I hope I placed it in the correct forum.

I captured some footage from CATV using the supplied software (AverTV) and the following characteristics:

Color format: Compressed(WJPG)...(other option uncompressed RGB24)
Video size: 640x480...(other option 320x240)
Enabled audio capture checked for CD quality (other options are radio quality and phone quality)

That's about it for options to select. Not much brain work needed here. When the video clip is captured, it saves it to my HD as an .avi file. Although there are not many options to choose from, believe it or not, the finsihed video clip is clean and the sound is great. Here is where my problem started.

Since this was an avi file, I thought I could use some of my DVD tools to demux the audio and video. Then I would drop these files into Maestro for handling and finally burn with Nero or other burning software I have. That was my plan. What I actually ended up doing was finding out that CCE would not accept the file as it was captured (.avi). So, I used my script:

aviSource("E:\CMT\cmt2002.avi")
ReSampleAudio(44100)

to wrap the file for CCE to use. This worked fine for downsizing the file. Although I didn't need to downsize the file to 4.7G, I thought I would test it anyway and it worked. But, I could not demux the audio from the video. Then I tried avi2wav to demux the audio and that created an audio file of type "wave sound". I thought this would work so I dropped the file into Maestro but maestro kicked it out. Then I went back to CCE and tried to demux the audio into a seperate file which I ended up with a sound file of type "Movie File (MPEG)".

And, this is where I am. So, in a nutshell, I started out with a video clip of type avi. After processing, I have either an audio file of type "wave" or type "Movie File(MPEG)". In case your interested, here are the CCE specs:
