Yes, my problem is Video Driver...
i use last ATI video drive, and i don't like ATI decision to eliminate standard control panel for a video board.
Now ATI support, develop and release only driver with a new control center, more beautifull in look and feel but develop in .NET and mroe heavy in termo of memory and CPU.
As suggest from troppo, i would like to try with ATI windows XP standard driver, that is list and show in Windows Update but i'm not sure about performance..
Did you think that this drive is equal to ATI driver in term of performance?
in MSP8 Video Capture module, i change to QuickCam Pro 4000 device and this work fine

Video Capture module stop to works only with ATI rage theatre capture device.
In ATI site i found this technote, but i have newer driver installed:
https://support.ati.com/ics/support/def ... olderID=27
i use WDM driver version: 6.14.10.6246
For the other my HW, no compatibility problem, i use this platfrom since 2 year and this are my only problem..... and ATI driver is my only changed...
Can you give me a feedback about Windows ATI driver show in windows update about performance?
Thanks again.
marco.
