Take a look at this pic I found of the actual box of the R22. I remember reading this same thing on the R22 when my friend had his installed. When mine was installed it was just in a brown box. You can pretty clearly see on the box it says up to 100 hours of recording time. :lol: I just thought it was funny that even directv didnt know how much recording time it will do. I know for a fact that the three R22s I have personally been around and used. That they all record much more then 100 hours of SD content.
