I recently had to return a purchased Archos video player with video-recording add-on hardware.
Videos of interview sessions (shot by us, using our video camera) were DRM-locked and could not be played back on a PC, Mac, etc. Anywhere outside the Archos player.
Vendor and Archos could offer no solution, though Archos acknowledged it was "a known issue". From what I gathered they simply don't plan on fixing it.
Not clear to me if the AVI's (apparently compressed with DivX) had Microsoft in the mix or not... But DRM successfully prevent me from using MY OWN VIDEO, and prevented a sale for Archos.
