4.49 GB is too big to fit on a DVD. When using file sizes as shown by windows a DVD can only hold about 4.37 GB of data.

Are you also including the size of your AC3 file?

OK but how com it increases 2 gig while moving it from my Document files to DVDA?
Also i think it is a bit strange that you cannot not fit a 1.4 hours production on a DVD. The project is rendered and ( the very few) text and transition parts should not take very much space...

Firstly you can fit 1.4 hours on a single DVD - with good quality.
You just need to use a bitrate which fits. It will need to be lower than what you used to create the 4.49 GB file.. that is if the 4.49 is properties from Windows. (Windows uses a "binary" calculation where the max is 4.37 GB; DVDA and disc makers use a decimal calculation of 4.7 GB).

If DVDA is telling you the project is 2 GB larger, there could be several things happening:

1. DVDA must be thinking it needs to render some of the files. Check with Optimize from DVDa. It could be thinking it needs to rerender the video, with a higher bit rate.

2. Audio? The audio will take some space; much more space if the audio is PCM instead of AC-3.

3. I've also found DVDA overestimates the filesizes.

You basically have 2 options:

1. Use a bitrate calculator to determine what rate to use, and encode your file in Vegas using this rate. The caluclators allow for size of the audio file, and some basic menus. Make it a bit lower if you have fancy menus.

2. Take your source file (e.g. DV .avi) file into DVDA, and let it render to fit to disc.

Option 1 gives you more control, and avoids needing to rerender later if for example you want to make a change to a menu only. Option 2 is easier.
