Does it work in graphedit (via render file)
Yes. And of course it works in WMP.
>What are the media types the filter is using
The filter uses a *.dvb file which is an XML description that it uses to pull data from the dvb-t card.
>Do you get anything in the MediaFailed event
Nothing. No exceptions, no mediafailed.

Good find. I am tempted to do the hour commute (it is 7PM) to just go try this out, I am that stressed over it :) I guess I will avoid risking the wrath of my wife and try it when I get in in the morning.
The filter by the way is this one (just in case you ever want a DVB-T filter) http://www.dsp-worx.de/ n=11 - The author claims it is alpha but it is rock solid on all of the cards we've tried it on. Obviously we can host in WMP, but if I can get it working in MediaElement then I can have all of the overlay niceness that I currently have (with alpha'd tickers over fading-in video).
I'll let you know, and failing that I'll drop Tom a line. WPF is a fantastic solution for Digital Signage and if I can get this working it could be on a few thousand displays soon (ish).
On a related note, whoever decided that the MS Press book on Directshow should be Out of Print should be told off - sternly :(
