Using Adobe Connect on a Thinkpad T410 with external cameras like Logitech Orbit MP (windows 7 driver or Eagletron DV driver(trial)), Sony DV camera would crash the plugin version 9.3 r139 or r268,
The workaround is to disable the internal webcam, you can then select the Microsoft DV Camera and VCR driver, you can use it as source. Thanks for Jason V. for figuring that out.
It looks pretty good with a Sony DSR-PD170. (video window supposedly only supports 320x240, and cannot be changed?)
