No sound for one file in completed DMF project

This is driving me absolutely NUTS....I am trying to complete a project in DMF 6, for which I'm using three video files, all of which I converted to compliant MPG format using Super!, making sure my project settings match the specifications of the input files.....and no matter WHAT I do, one of the video files ALWAYS comes out in my final ISO file with no sound! This particular file was an .mov/QuickTime file I converted to MPG, and the other two files were WMV and AVI, but both of those HAVE sound in my final ISO. I have tried reconverting the one file from the original MOV file as well as taking the converted MPG and re-converting it back and forth several times, but no matter what I do, DMF gives me NO sound on that file in the output ISO. Take note: The converted files as well as the originals ALL have sound both when I view them outside of the DMF program, as well as having sound when viewing them in DMF (in the preview window)....but still the one file never has sound in the final output.

Actually, add to that another project I'm working on for which I also converted several files of various original formats into compliant MPG....and four of those files also came out in the other project with NO sound. I tried recoverting them, but still had the same problem. I even tried using Any Video Converter instead of Super!, and replaced the problem files in the project with the ones converted through AVC, and same thing. Tried clearing the temporary working folder and temp files for DMF, and no luck....same thing happens with both projects.

What the heck is causing this to happen, and always on the same files? This is the first time this has happened to me, and the first time it's happened with video files converted through Super!....which has never given me any major problems so far. Also, on these problem files which end up with no sound in my final ISO, I've also attempted using both filters in Super! (the FFmpeg and the MEncoder options), and neither one makes any difference. Have also tried different bitrates and sampling rates, etc. (although I try to keep the conversions to match the DMF project settings).....NOTHING makes any difference. The problem clearly seems to be in DMF itself.

HELP!

The only thing I can suggest is to try creating a separate WAV file with SUPER. Then, use that file for your audio with the problem clip.

Yeah, I guess I can try that, Doug (thought about it).....but the question/problem still remains as to why the one clip in the one project and the four clips in the other project are doing this when everything else that does work has been converted to the exact same specifications as the clips which don't work. There has to be some reason, and the reason has to be with DMF. I even tried reinstalling the DMF 6 patch and still had the same problem.

I'll give the wav suggestion a try and post back here with the results....just in case.

ADDENDUM: I did a test run and it WORKED, Doug....but instead of using Super to rip the audio in wav format, I did it as an AC3 file, and it DID work. Thanks for the suggestion.....the question still remains as to why DMF isn't recognizing the audio in the converted files, though (Note: I ripped the audio from the original files, not from the converted versions).

We'll probably never know why... All I know is SUPER has "saved the day" for me, more than once! Last weekend, I was having trouble extracting the audio from an A/V file with Video Studio. Then, I thought of SUPER which worked perfectly!

You'd probably need some sort of tool/program to analyze your files and tell you what's different about the problem file. And, we don't know what's going-on "insided" Movie Factory either. (I'm a moderator, but we are not Corel employees.)

BTW - I usually recommend WAV files, because the less-compressed files are generally the least trouble-prone. They are the easiest to edit or convert/compress to other formats. The same is true with video formats. AVI/DV (13GB per hour) is the most fool-proof audio/video format.
