    I'm sure that Blackmagic's capture boards are great pieces of hardware. We also have a lot's of questions about our lib and their boards but you must understand that none of the lib writers (or at least me) have such hardware. So it's really hard to help you. I think that you should be able to ask some help from the Blackmagic's support.

    Note to Blackmagic PR: if you want us to help your customers, send us some samples boards !

    Thanx for your reply. After long try i found a solution, I can make graph using graph edit tool and it is suffecient as my need.
    but one help i need is, I want to use GMFPreview Sample, but this can only preview video on picturebox screen, I also want to add onther renderer filter (Decklink Video Rendere) to the graph. when i add the filter, it is added to the graph,but when i see the graph in graph edit there is no any connection, I just need How to connect this way:

    Video Capture--->Infinite Pin Tee Filter--->Smart Tee-->Bridge Sink
    | |
    | |---->Video Renderer(PictureBox)
    ----->Charecter Generator-> Decklink Video Renderer

    Kindly help me, will this be possible using GMFPreview, If Yes then how should i connect these fileters. Or Should I have to go with aonther way.
