Flash Player 10 crash once i give it the permission to use the camera

I'm using a videoconference service using Flash Player 10, and when i want to turn on the cam, it ask me to

give the permission to Flash Player to use the camera.

Each time i click the ALLOW button, Internet Explorer hang (I've tried with Google Chrome, i get an error too).

Here's the Error Signature that i get...

AppName: iexplore.exe               AppVer: 8.0.6001.18702               ModName: flash10c.ocx

ModVer: 10.0.32.18          Offset 00148950

The error is always the same, and happen at the same moment.

It work just fine with my Dynex 25$ camera.

But when i try to use my Samsung HMX10A camera with a capture device (ADS Tech VideoXPress), i always get this error.

This device work just fine with other applications... but everytime i use a Flash application, bam!  It crash.

Does anyone have an idea?  How to solve this problem?  Is there a list of SUPPORTED CAMERA DEVICES for Flash Player 10? (I've seen a list of completely outdated v6 only on this web site).

Thanks a lot
