I want to write an application that captures video from a camcorder, overlays this stream with some graphics including text and bitmaps, and then writes the resulting stream to both a preview screen (preferably in real time) and a file. Currently my system, written quite a number of years ago, achieves this using a genlock adapter to mix the graphics (generated using the MFC HtmlView class) and video stream together which is then captured on a Video recorder. I'm hoping that nowadays PC hardware and software are more than capable of emulating this in the one piece of kit and that I can then copy the resulting files to DVD for distribution. I've looked at DirectShow, VMR-9, the documentation and the samples for capturing streams etc. but have ended up more than a little confused; I'd appreciate any advice as to which methods of overlay, rendering and preview I ought to use, or perhaps a pointer to some other examples.

You might want to post this to the ../video group although a Google Groups search will show that it has been asked and answered there before.
Thanks for that. you're quite right I should have looked there first.
