I have found that Windows 7 can do a "Play to" on media files to send the output to my WD TV Live (plays video to my TV). I have now done some experiments and found that it appears that files on the local disk is accepted, but the same file on a network drive is not accepted by the Play To window where I try to drag/drop the file to.
Can I Play-to for non-local files or is that not possible?
