Can you transfer recordings from the newer TiVo's (Roamio & Premiere) to a series 2 Tivo? It's a TCD649080 I have ever the opportunity to get a series 2 that has lifetime and I'm interested in putting it in my office/workroom and hopefully just watch recorded content from my other TiVo's that are on cable. Will it only work for non-hd content or will it work with HD recordings? Since the series 2 has ethernet and would connected to my network just no cable since my cable company is all digital. I could get another mini but prefer not to If this cheap series 2 with lifetime will work with the newer series 4 & 5. Just curious if it would be worth getting, again it would be just for casual viewing existing recordings and not live channels. Thanks!
