You need 'DVD Patcher' - [url=http://www.videohelp.com/tools/DVDPatcher]

Just make sure that the un-changing parameters match old->new before you hit the go button....

You can change the aspect ratio within DVDA. Use the OPTIMIZE DVD screen and change VIDEO settings.

Yes, but that means DVDA recompresses the MPEG file - DVDPatcher just modifies the MPEG headers (very fast & no quality loss) to fix files that have incorrect header information.

It's also very handy for changing the bitrate info in the headers when using apps that smart-render MPEG files (which now include VP8 - hurrah!).

Well in my case the Project was setup as 16:9 and the file was encoded out of Vegas as 4:3 even though it was 16:9 so the DVDA project was correct and in fact DVDA will not recompress the footage, it'll tell the player it's 4:3 (it seems you can mix 4:3 and 16:9 on the one DVD, not a good idea in my opinion) and it'll get displayed wrongly.

I downloaded the utility but it was 1 am so rather than learn a new tool I did the re-encode while I got some much needed sleep. But thanks for the tip and John for some offline ideas. I will get to know this utility so next time I have a solution at hand.

Tony,

Changing the AR setting does not require re-encoding. The resolution of a 16 x 9 or 4 x 3 video are the same in standard def.

It only changes a flag to tell the DVD player to play the video at a different aspect.

Yes, I know - the point I was making was that DVDA won't let you change the AR setting of a media file unless 'Recompress' is set to 'Yes' (the option to change the AR is greyed out otherwise) - using DVDA 4.5a with DVD-compliant MPEG files.

You might be right, let me test it. I know i have done it without recompressing but let me verify.

Weird - what are you using as media files, and which version of DVDA is it - just out of curiosity ?

I edited my comment after you responded I think. I am testing it now to see, but I was sure I have changed the aspect without recompressing, but I have been wrong before.
