Compressed Project won't fit on DVD

Question

I edited a FCP project that ended up timing at 1hr. 59 minutes, and 27 seconds.
I exported the project using Compressor, and chose my presets as MPEG-2 120min High Quality encode (choosing "All" for both video and audio).
I then brought this into DVD Studio Pro and proceeded to make the menus and chapters, etc.
First Question: I was surprised that the compressed audio and video were seperate (an aiff and then a m2v). Is that supposed to happen? Did I do something wrong since I had to add the aiff file seperately to the DVD?
Also, now that I have both on there, I'm being told it's too large to fit on the 4.5 GB DVD. My MPEG-2 file is 2.92 GB and my aiff file is 1.28 GB. Plus the templates are using some minimal space.
Is this because my project's too long? Or did I choose incorrect settings?
I then tried the fast encode because I thought the file would be smaller. That didn't work.
One more question! What kind of discs are compatible to burn in the super drives?
I had some TDKs, but those didn't work on another project I tried to burn.
Thanks!

Answer 1

It sounds like you're using Compressor 1 (or some variant, like 1.2). Please confirm if that's correct.
If that is the case, your fix might be an easy one. Locate a program called A.Pack on your machine (it should be in the Applications folder) and use it to create a Dolby Digital file.
If you use the .ac3 file that A.Pack creates, and delete the .aiff file from your DVDSP project, that should save you more than enough space to burn your project onto a standard DVD-R.
As for what kind of discs are best with your SuperDrive, that's a bit of a crapshoot (because different products lines from even a single manufacturer aren't guaranteed). But anyway, I've had great luck with Verbatim's DataLifePlus series (I usually get them from B&H).
