Vegas 15 crashes and needs a restart when I tried to open AC3 audio file. V13 and V14 give a message unsupported file but do not crash the application which is much better. Bug?
Previous versions of VP did not support opening AC-3 audio files, though it could render them. Not sure about VP15. If you 'really' need to open an AC-3, there are conversion utilities available, both on-line and install (free and for purchase)
The problem is that if the patient is deceased Vegas15 closes the surgery and goes home where as Vegas 13/14 says patient deceased - next patient please.
