How I wish I'd discovered DVDRemaster a few weeks ago when I was trying to burn a 7GB iDVD project onto a single layer DVD disk.
In the end, I had to buy a Double Layer DVD which is a) Expensive since they're often only sold in packs of 5 or 10 and b) Annoying because DL disks don't always play properly on all DVD players. It would have been far preferable to have shrunk the project into something that could fit on a single layer DVD and that's what DVDRemaster aims to do.
DVDRemaster comes in two versions - Standard and Pro. Pro gives you more control over how your DVD is compressed - for instance you can discard selected video and audio tracks - but most users needing a simple compression job will be fine with the standard version. DVDRemaster doesn't just compress for DVD playback however - it also re-compresses large DVDs so they can be watched on your video iPod, iPod Touch, iPhone, Apple TV and more. The interface is slick and throughout, DVDRemaster is a pleasure to use.
Unfortunately however, you can't compress iMovie or iDVD projects directly. You'll have to convert your creations to a Video_TS file and then shrink it from there. There are several easy to follow tutorials though that make this very simple to do. DVDReamaster also comes bundles with Fairmount which helps decrypt heavily encrypted DVDs.
DVDRemaster is a great solution for anyone that's ever needed to shrink a DVD for single layer burning or reproduction on their mobile device.
