I have the DirecTV DVR deal, and I love it. Problem is, a few days ago it started to slow down. I only have 4 shows or so on the HD, and I don't know what's causing it. It's not recording anything new, and if I try to play something already stored, it pauses for a bit then goes back to what I was watching, or sometimes a channel lower/higher. Any idea on what this might be and/or how to fix it? Any and all advice is appreciated. Thanks!
