So far:
Rendered audio to AC3 with V14 for Blu-ray disc. No longer got to select bit rate or specify Dialnorm -31, but tried creating AC3 audio file anyway. DVDA didn't like the AC3 file, and said it would rerender audio, so instead I rendered audio as stereo .wav.
Went to create DVD version of the project. I tried to use to use the MatchAspect.js script to handle the aspect ratio conversion from HD to wide-screen DVD. The script no longer runs -- "Variable 'TrackEvent' has not been declared", etc. Have to change each event by hand.
Anyone else encountering these problems? Also sad that the Magix forum makes it so hard to see more than a few posts at a time.
