I recently downloaded the entire Elfen Lied series, and I am now making a few dvds for me and some fellow anime-loving friends. I am using the titular program to accomplish this task, however I have run into a problem. Even though the total size of the files I have set up to be on the dvd is only 3.06 gigabytes, the program is telling me that the finished product is going to be 20.9 gigs. Obviously this will not even come close to fitting on a dvd. Any ideas?

It's probably the DVD formating that is to blame for the expansion. Much like when burning audio CDs the files need to be decompressed so they can be read by a player. How long (time) is video series you're putting on the DVD, and what format are they encoded in? You could fit them all on a single DVD as data files, but then you would require a PC or a special DVD player to play them back again.

The episodes are 25min a piece, 13 episodes total. Each of the episodes are encoded as .avi files, and they are around 240 - 250 Mb a piece. Since there are 13 episodes, this comes out to ~3gigs.
Considering these statistics, I should be able to fit all of the episodes and background art (for the dvd menus) on one disc, with no compression. I have even tried to split the series into multiple discs, but I have to get it down to 2 episodes per disc before it fits (and then just barely).
This means that the software is considering a 240 mb .avi file to be around 1.7gigs.
Is the software just grossly miscalculating, or am I missing something? I can send you (or anyone) the .dar file (the project file for Sony Vegas) for this project if you would like to take a look at it.

when a video program re-codes a file, and you do not re-compress it, it will make VERY large files... I have this issue when I am "warping" my high speed videos in Adobe After Effects, as I do the video splicing and dicing in Premiere, I have to leave them uncompressed for best quality - they start between 10 and 100 MB a piece, but after being run through a video program they get up to 2 GIGs Minimum... most are larger!
check your final output compression settings, and do NOT leave it at uncompressed... that does not mean it is going to compress it more, but that it will keep it at the same compression it is right now (consider your AVIs as archive files, when you choose uncompressed when saving them, what happens? they get bigger... just a little analogy there)

exactly what uzzors said, its not like the cd or dvd player has a windows API and somewhat powerful hardware to support all the codecs, so it must be decompressed into raw audio files. in addition, it has to add track information(that can be read by the CD player) as well as track numbers and information and such. as a result, your limited by runtime not by file size. (hence why cd's say 80mins on it)

Oooh, did not know that. I'll get on that right now.

Your AVI files likely use a very efficient compression algorithm like DivX, which is what lets you squeeze lots of video into a few hundred Megabytes. This is fine if you have a PC with the right CODEC installed to perform the necessary DivX decoding and play the files back.
Once you come to putting the episodes onto a Video DVD the application used to burn the disc will decompress the DivX files and then recompress them in MPEG-2 format to play back on a standard DVD player. The problem here is that MPEG-2 compression is not as efficient as something like DivX, so the resulting files will require a lot more space. On the positive side the resulting DVD should comply with the Video DVD standard and should be playable on any hardware DVD player or suitably equipped PC.
There may be an option somewhere in the DVD authoring software to tweak the MPEG-2 compression settings so that you can trade off some quality for playing time. In my software there are options like "HQ High Quality", "SQ standard quality", and "LP Long play." If you have something similar the LP option might let you squeeze the maximum length of video onto the DVD.
You basically have two options, either burn the episodes onto several Video DVDs that will then play on any standard hardware DVD player or PC.
_OR_
Burn the actual AVI files onto a single Data DVD which will then only be playable on a PC with the appropriate CODEC like DivX installed, and possibly a limited number of hardware DVD players that are emerging that can decode DivX MPEG-4 etc

If I recall correctly, most DVD players can play non-DVD standard formats... every one I see now has some kind of non-MPEG2 codec listed... I am sure there is one they all have in common that is not Mpeg-2.
