Error when changing the options of analog video cap. device

#1
Hi all

I get the following .Net exception when trying to change the device options for the analog tuner device:
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
I'm using a Hauppauge HVR4000- The following device is activated in the device list: Hauppauge WinTV 88x Video Capture in

The first three lines of AnalogTuner.log show:
Error
Can`t set TV Format
Filter Hauppauge WinTV 88x Video Capture
