Dear sir,

I am using ReceiveConnection to change only video dimensions while graph is active. It is working fine for me, but sometimes while changing format MSVCRT.DLL is crashed with EVR (in vista and above systems.) and Quartz.dll crashed with VMR9 in XP systems. These issues are frequently happening, I can't continue without fixing these strange issues. I need to know why it will crash, whether it is bug with video renderer filters.

If you know the solution to fix these issues, please give suggestions.
Awaiting for your reply. Thanks in advance.
