I have exactly the same issue with OL CS5 on both my laptop and and workstation when capturing HDV from a Sony Z1. I have disabled anti-virus and diskeeper, to no avail.
As with you, OL on my workstation doesn't even attempt to drop into record, it just freezes. At least the laptop attempts it, but it soon crashes.
As stated in a recent thread, so far, my only workaround has been to reinstall OL CS4 on my workstation. Works like a dream. Today I'm going to do the same on the laptop and see what happens.
Anyone from Adobe TS here?
This is most likely the result of OnLocation seeing a webcam or some other device/app as a video device, which interferes with normal operation. In short, it's a bug in OnLocation CS5.1. If you have a webcam connected or integrated, disconnecting or disabling it should resolve the problem.
For a little more information, please see this post: http://forums.adobe.com/thread/638230?tstart=60.
P.S. I do NOT have a webcam connected to this computer.
Nope, desktop workstation. No webcam. It just freezes the system.
Does the Devices list show anything other than your Firewire-connected camera? Webcams are the most common thing to be enumerated there, but we've had reports of programs and other devices also being in the list, and they result in the same bug.
Are you sure that the GFX card is compatible? That was the problem with my laptop.
GPU is definitely compatible, Nvidia Quadro 4000. That shouldn't matter though should it? People are capturing on laptops
