I have had my Series 3 since they came out... never a problem. Plain vanilla stock unit... no mods except adding an external eSATA a couple months ago. Just yesterday it started acting funny... slow operation. Rebooted once. Now when I power cycle it, it goes through the entire start-up... through "just a few more minutes"... does teh THX logo... then the Tivo animation... then comes to the orange screen... the menu takes about 20 more seconds to show up. Once it does, the remote and rfromt panel controls do not do anything. First item "Now playing" is highlighted but nothing I do has any effect... no remote or front panel buttons. It also appears that the background smoke animation is moving slow and jumpy. Any suggetsions on what I can do to fix this?
