Hi Craig,
the Mac PRO that i was using is old.. OS is 10.5.8.
So would be a long way to adapt that mac to the specifications you told me.
I realized that a Mac PRO in editing room, the newest where I work, is actually Lion 10.7.5. So I decided to make tests with that mac, with Wirecast 4.3 trial and brought the same panasonic HMC80P. The result was that after many tries I could not reproduce the issue of the thread.
I saved the project without even turned on the camera. I opened the Wirecast and then turned no the camera. I turned off the camera before close Wirecast.. But the camera signal always come back perfectly.
Well, considering that in the cases I wrote first, where the camera was always recognized at System Profiler, the issue doesnt point to a hardware problem.
Seems to be outdated software issue
Thanks for the attention.
