Looks like the days of cobbling together apps like TCPMP and Zbop's Flash Video Bundle might be going the way of the Foleo....

www.vtap.com - they have a very nice WM cab file that front ends searching for AND PLAYING videos. YouTube - all of 'em.

Grab the cab file for your device of choice and check it out. Go to their URL on your device and OTA it. Sweet.
