Hi Jon,
thanks for the help. Unfortunately, repairing disk permissions did not help. It also has difficulties, i.e. will not repair all disks and not all errors it spots.
Regarding re-installing: We have installed it on three different Macs, all having this problem. The CS5 that was on there before had been uninstalled with the cleaner tool.
First results: Mercury hardware acceleration could be the problem
When we reopened the underlying projects and changed the MPE setting from hardware acceleration to software only (project settings), it seems to encode stable.
We have NVIDIA Quadro FX4000 for Mac and Quadro 4000 for Mac boards installed. Problems show on both configurations.
Maybe there is a bug with the NVIDIA cards, their drivers or Adobe’s way of adressing them?
However, I do not see how I could nail it down for a qualified bug report to Adobe. Any ideas how this could be communicated to them?
Regards,
Andreas
