Well this should be post about 1-2 days ago after Fabio Sonnati post this in FlashComm mailinglist. It’s about VHScrCap an alternative driver for screen capture driver with are compatible with flash player and available to share in flashcomm application using Camera.get() the as we did with Camtasia driver.
The good point compare with camtasia is that VHScrCap is free for personal used.

Today Vladimir Hmelyoff, the developer of this driver give a solutions about how to enable setup tag (x & y coordinat, with & height, fps, the VHScrCap. Beside using AMCap he also provide us to use VideoWDMControl. And my opinion the last one is much better.
