Thats the same for me but when i open it it only does audio and no picture lol

OK UPDATE...

this is not a fix but more like a back door. Depending on the complexity of your video this might not work for you.

Download THIS and open your video.

Then under file save WAV...that will make just an audio track of your vid.

Open your vid in vegas...then open your Wav you just made. Depending on how your video is layed out there might be some minimal syncing involved, but I have done this with two seperate ones now to test and it has not been a problem.

If you try this and need more help just let me kmow. Also, If I find a way for vegas to open files properly I will post here.
