[QUOTE="samuel337, post: 14335, member: 10347"] Um... have you actually checked out DVBGraphBDA.cs yet? The TV card is being accessed using DirectShow by creating a graph. It builds the graph using information from CaptureCardDefinitions.xml, using (I think...) the DirectShowUtil class to do build it. DirectShow connects to the card via the BDA drivers itself - no work is done by MP; MP simply tells DirectShow what to do. If you check out that file, and track down the various functions that it calls (most of them are in the Core project) you should get a pretty good idea. Of course, understanding all the DirectShow terminology (e.g. filters, graphs, pins etc) would be helpful - do a google search and there should be some good info out there. HTH Sam p.s. it's nice to be humble sometimes, but this time I'm really not an expert on it because I haven't really checked that bit out ;-) [/QUOTE]
