Apple has updated DVD Studio Pro – its professional DVD authoring application – to version 3.0.1 and recommends that all users install the update, available from its Web site or the Software Update feature.

The company says the update improves stability and compiling when using long MPEG-1 video clips or compiling tracks with a transition on a still image at the end of the track.

The update also ensures that burned DVDs mount successfully on Mac OS 9 – before it was necessary to select Command-Option-I.

Other enhancements include resolved memory issues, improved simulator support for playing 4:3 tracks in PAL 16:9, and the ability to add MPEG files from the Finder to a Drop Zone while Motion is on. A full list of changes is available here.
