Video Data fired from COM Dll not received in my ATL project in VC++ 6.0

[NarayananDurai]

Hi,
I am facing one strange problem in Vista (Business edition).

I am developing one ActiveX control using ATL COM wizard in VC++ 6.0 to display the video packets received from COM Dll called Adapter. Internet explorer is a client for ActiveX control.
This scenario is
Logs show that Adapter is firing the video packet.
ActiveX is not able to receive the packets from Adapter.

(Note: 1. Both the adapter and Activex dlls are successfully registered
2. Error events like packet loss are received properly in ActiveX)

The same scenario works well in Windows XP. It is expected to work with the default internet settings in Vista.

what may be causes for that problem?. How to Overcome?.

Please help me with your comments and suggestions

Thanks
Narayanan
