Have a useless UVerse DVR VIP1225. What can I do with it?

I was wondering what I can do with a DVR from UVerse I was FORCED to purchase and I cancelled the service and they will NOT refund my money but they said I can send it back to them. I told them to kiss my A$$. Is there any hacks or anything to make it a media player or to stream movies or anything like an apple tv? Does it have any other uses that AT&T does not intent or WANT to happen to it? As soon as my wireless contract is up, I'm moving to Verizon. AT&T absolutely SUCKS BAD. I've had ENOUGH of THEM..
