Google Play videos on the MK802

I am thinking of purchasing some tv shows on Google Play.  I have been reading up on the DRM and I'm a little worried.  Purchased media is stored in a private area on the SD card.  If a pirate wanted to get access to the media, they would need root access.  To prevent this, The Google Play media player will detect if the "phone" is rooted, and it won't play the media if it is rooted.  Many people in the online forums talk about "unrooting" their phone when they play a video.  This causes two problems for me:

1) I want the Android TV to be as easy to use as possible.  I don't want my wife to have to go through some procedure to "unroot" the device just to watch something

2) You may be wondering why I rooted the device in the first place.  There is an easy answer to that: the device comes PRE-ROOTED.  The 1st and 2nd generation MK802's come factory rooted.  This poses another problem: how do you reverse the process?  How do you "unroot" a device that never needed to be rooted?

I have gift cards for the Play Store, but how do I bring myself to pay for such crappy video?
