Because of the DRM protection, the TV shows purchased from iTunes can not be played on non-Apple devices unless authorized. But each account can only authorize up to 5 times. Therefore, if you want to enjoy iTunes TV shows on PSP, HTC, Zune, Blackberry, etc, what you need is a DRM converter instead of a regular converter.
