I went to change channels and noticed that only the channel I was tuned to showed up in my guide. I switched to "Channels I Get" and it populated the guide. Upon close inspection, I found out that my Custom list that I meticulously whittled down to the essentials is gone!
According to my wife, the system automatically re-booted today but for some reason, my favorites list went with it.
I'm using an external drive, so I'm going to try re-booting with the internal to see if it restores my favorites list and then going to switch back to my external. We'll see what happens.
Anyone else have any ideas regarding how to recover the favorites list?
Probably the worst part is that I went through the trouble of making a spreadsheet indicating all channels available and which of those were included in my favorites list. Now I can't find it...don't ask!

Thanks!
