Best way to record UFC TV PPV events?

I know about DVR's but I want to be able to record the show to DVD/BD as I am watching the event.

Buy a dvd recorder. Phone Post

I purchased a Vulkano Flow (like a Sling box) for $100 on Ebay.  One of the coolest features it has (other than being able to access and stream video directly from my Uverse receiver) is that it can record anything I'm watching to my PC hard drive as an MP4 video file in very high quality.  You can then use your computer (equipped with DVD or BD write drive) to burn the file to your preferred media.
