Tivo HD has had a green screen for a while now. When it first happened, I contacted tivo. While I was on the phone with them, they asked about the db which is currently at 29. I think he said it should always be at 32 or maybe it was 35. At that point though, the color came back (my only concern atm) so, I let him go. I poked around a little and found out that the green screen probably means the hard drive needs to be replaced. My question is, will repelacing the hard drive fix whatever the problem is with the db? And, what exactly is the db?
