i am sure this has been discussed but i am hoping for some friendly and helpful advice. i have toshiba sd-h400. have recently converted to broadband via my new wireless network. my tivo's remote has died and i have ordered the urc-6131n. i would also like to switch from the ir cable to the serial cable and have verified that my cable box will support that. now i would like to add a 2nd tivo in another room which i will get a 2nd tivo adapter to connect to the network. my dilemna is that i have paid lifetime service on the first box so i am trying to keep that foremost in my mind. i like all hope for the eventual opportunity to upgrade and transfer at some point but know that may or may not happen. i don't mind the fee for the 2nd box as i love my tivo and got the service and first box for great buy anyway. i have been considering buying a 2nd sd-h400 while i can in case i ever need parts for the first box to keep the lifetime service, but does that make sense? what parts would i use? or am i on the right track? if i did get to upgrade then i would still just have the 2nd unit. of would it make more sense to get the 2nd unit as the upgrade box and keep the 1st in the backroom just to keep connected to lifetime service. in that case should i be concerned about replacement parts to keep that box in service for years to come? whew! i hope someone has the patience to sift thru this and offer their thoughts. thanks so much! ps- i also have a 42" plasma, a 2nd dvr, home theatre and some connection issues if someone would like to direct me to the proper place to ask for help in that area. seems the more i upgrade the more issues and confusion i have.
