I have a HD TIVO model TCD658000 which has just died - no lights on front panel and only the hard drive is spinning. I talked to Weaknees tech person and we tried a new power supply which did not fix the problem. We now think it is a motherboard problem. My question is, assuming the HD is OK, if I can find a working replacement used TIVO (eBay, Craigs list) can I install my old HD and use the second TIVO to play the stored programs on my original HD? I am looking for a way to watch a lot of stored programs on my failed units HD. Thanks for any help.
