Hey all, So my DVR40 started acting up this morning -- it is stuttering everywhere: playback of shows (including ones I know where good yesterday), menus, live TV. I'm assuming that this is a HD problem and that's where my problem is. I have an upgraded unit with a second HD. How do I determine which of the two HD's needs replacement? From reading the forums it looks like most HDs will pass the PC-based disk checking tools. And I'm not getting an audible click of death to narrow it down that way. Second: Is there a way to keep my season passes when replacing either the primary or secondary HD? I don't care about keeping content, just don't feel like readding the seasion passes. Thanks all!
