My Tivo Premiere last night froze up twice; once when doing a search, and once when accessing my programs. After a about 30 seconds of it feezing up, the TiVo rebooted. I ended up switching to the SD menus, and everything has been find since then. Up until last night I would get freezing issues (the spinning circle) but after a few seconds it would work fine. Last night was the first time it ever rebooted. Has anyone ever had this happen before? I prefer to use the HD menus, but can live with the SD menus if that is what I need to do. I am just wondering if something else might be effecting it. Or it is was some sort of commucation error. Thanks in advance.
