I received above error with Recorder.
I had been using recorder with both my capture device (a USB device connected to my VHS camcorder), and with Microsoft LifeCam Cinema webcam - with no problems.
I then decided to try editor, with the view to purchasing the programs.
At about the same time I tried Debut by NCH. Decided I did not like it. So uninstalled.
Now when I try to capture using AVS Recorder I get the above message.
I have uninstalled everthing, all drivers, software, etc. including the LifeCam Cinema webcam; but I still get that message whenever I attempt to engage the capture device.
By the way, the capture software that came with the device also hangs now, although it worked before as well.
Seems to me that something has grabbed onto my capture device (probably a Windows registry entry), which I cannot uninstall. Also used Ccleaner, etc.
By the way, the device is EZ Grabber 2 by geniatech http://www.geniatech.com/pa/ezgrabber2.asp.
Cheap; but it was working fine until this inexplicable problem.
