File size differs in DVDA Studio 3.0

I have several .mpg files I have rendered for DVD authoring that are about 350MB in size. However, when I drag even one of these files into DVDA Studio 3.0 it shows that I have used 1.6GB of disk space so far... (Thus I can only put 3-4 of these fiels on a disk)... There was also the odd file I brought in of the same batch of 350MB files that showed I used 600MB of space... I am wondering why DVDA 3.0 thinks that the files are larger than they are... A friend's computer with DVDA 2.0 recognized the files as the correct size, so I wondering if anyone knows why 3.0 gets so confused as to what size the files really are... I have tried updating 3.0a to 3.0b but no change...

There are (at least) two possibilities:

1. DVDA Studio 3.0 is just wrong, which most flavors of DVD Architect often are. It gets better at estimating project sizes with each version, though, and if your friend has the 2.0 release of regular DVD Architect, that's actually based on, I believe, better code than DVD Architect Studio 3.0. If the files truly are 350MB, and DVDA doesn't have to re-encode them for some reason, then go ahead and prepare / burn the project.

2. As implied above, perhaps DVDA has to re-encode those files for some reason, in which case it's going to use its default bitrate which is probably higher than that used in the files you have. Higher bitrate will result in the end result having larger files.

Hard to tell -- you don't say anything about the files other than that the "are about 350MB in size." How long are they? What framesize are they, and is your DVDA project set accordingly? What bitrate are the encoded at?

And most importanly, when you go to File -> Optimize DVD, what do you see? A buch of check marks or a bunch of exclamation points? If you see a bunch of exclamation points (particularly in the video column), that means that DVDA considers your files not to be DVD compliant or their properties do not match your project settings.
