Klaus, Im testing your plugin under win 7 and Im only able to open the crosshair screen, no video feed. Mach default video works ok.
To be able to see the crosshair I need to start the mach default video plugin first, otherwise camera is not detected by your plugin with a "No Camera Found" error messagebox
Is there something I can test?
my Setup:
what version of Mach3 are using 3.042.029
what is your processor speed intel quad core i5
how much RAM do you have 4gb
what display adapter nvidia 9500gt
and how much Video-RAM are you using 512mb
Windows 7 ultimate
Thanks!!
