I did a 30 minute export using compressor last night. I have not tested A.PACK yet, but the everything else, creating the DVD, all ran perfectly.
I installed fcp4 first, as an update to 3 and dvdsp 2 after as an update to 1.5.2. I just took the defaults...nothing special here..
I am all patched up. I am on Compressor 1.0.1.
DVDSP is version 2.0.0
Interface: 163.0
Authoring 161.0
Base: 163.0 (encoder: 212)
Oxygen: 159.0
Are you all patched?
