Though I rarely post, I've been around for several years. Don't let the join date fool you, I had forgotten my user ID and password from way back and the email address that I used has long since been deleted so I had to re-register.
So my TiVo HD's (TCD652160) hard drive failed and I replaced it (perhaps temporarily) with a 250GB one that seems to be working OK. The darndest thing has happened however that occurred on the old drive and I am now seeing on the new drive. As the old one began to fail, I would get stuttering vidoe, pixelated recordings and all the usual symptoms. The other odd issue that I had is that when I went to TiVo Central, I could see (and navigate) the menu, but the background was the current channel broadcast and not the blue (I think) wallpaper.
Having replaced the drive, the pixelation and stuttering are gone but the lack of wallpaper/background persists. The TiVo, in every other way seems to be functioning perfectly normal.
I'd consider this little more than an annoyance, but it's often rather hard to read the menus. Any ideas?
