V4 Cannot read MPEG file that V3 could ...

Used VV3c to edit a kid's christmas show. Original file was 210MB, could be read fine by VV3c, by TMPenc, by WMP8 & 9, by ... Having now installed V4, it cannot open the original VEG file as it reports it cannot read the file.

Tried to create a new VEG file by opening in trimmer as well, to no avail. Get same error. Just to make sure, went back to the original file that teacher gave me on CD, no corruption, V4 cannot read the file off the CD either.

Every other MPEG file I have come across opens fine. Am fully registered.

ANY CLUE AS TO WHAT IS HAPPENING?

You can't open the .MPEG file, or the .veg file?

I cannot open the MPEG file. The VEG file can be opened but only with the MPEG offline ...

Even if I ignore the VEG file and just try to open the file a "popup" display says file cannot be read

Thanks

is this MPEG an elementary stream? If so, Vegas will not be able to read it. Convert it to a program stream with TMPEG and you'll be able to open it in Vegas.

If the above post doesn't fix things...

I'm assuming that after the VV4 install, VV3, winmedia etc. continue to play the mpg file. If not, then I'd look to see what changed -> the default decoder may have been overwritten in the registry for example.

The main concept file installed by VV4 may be incompatible with older mainconcept files installed by another app (prem for example). In the latter case, might look for main concept files in the system or system32 folder in your windows directory and try changing the file name extensions and give it a try.

Is it possible that something video related was installed whilst VV3 was in use, but before VV4? Imagine in that sort of situation something could have been installed to the VV3 plugin folder that VV4 doesn't have.

After copying the mpg file to your hard drive, you might also try renameing the extension, &/or possibly changing the fourcc code in the file's header using one of the utilities at digital-digest.com. If that fails, the site also has utilities to *repair* mpg files -> this one may be slightly out of spec, or at least what the VV4 mainconcept stuff thinks should be spec.

Thanks for the advice. I'll try it.

Had VV3c installed. Installed V4 and removed VV3c. All other MPEG files can be read, this one cannot. It is MPEG-PS not elementary stream.

Perhaps there is slight irregularity as you raise. I'll try but since everything else is working and VV3c could read file fine, my gut is that there is a bug here.
