After following the steps in this thread (http://thegreenbutton.com/forums/thread/287574.aspx#287953) I can now play mp4 and h.264 files. However, I am still not able to play .M4V video podcasts which I have downloaded.
It has the same entries in the registry on the machine as mkv and media center shows the file in the download directory, but I get the dreadded "Cannnot play video. Media center cannot open the file" error....

Can anyone help?

Thanks
