USB Camera Control Settings Issue (OSX - W7)

edit

Hello Forum!!

I'm writing because I have an strange issue with OCV.

First let me set the scenario.

I have compile openCV 2.4.4 for Windows 7 for VS Express 2010. Everything was ok. OCV working well.

I have compile openCV 2.4.4 for MacOsX 10.6.8 for XCode 3.2.6 Compilation was ok. OCV working well.

I have a USB 2.0 camera LI-0V5640 5MP, with 720p and 1080p resolution. I have write a test program like shown:
