Well, I've seen messages about updating channels many times before but this afternoon it gave me something like: Updating Library - this may take several minutes to complete And it did take 2 or 3 minutes and big surprise, after it was done all of my recordings (two Stern shows) were gone. That's the 3rd time in as many weeks that I've lost all recordings. My faith in it has gone down to zero - in fact if my timer does work and does record without erasing my other recordings it's like a pleasant surprise. But back to the issue at hand, what does "Updating Library" mean? H'mmmm - this unit is a major disappointment. I wish my SL100 had never gone wonky. I'm missing my SL100 now and even though it was bigger, clunkier, and ran a lot hotter, I sure wish I had it back.
