I have a TiVo Premiere. I have backed up some shows (like my Blackhawks playoffs games this year!) to my computer, using TiVo Desktop. I then copied those files to a 2TB external hard drive. My question is, is there any way to play back those files from the external on my tv? I'd like to remove them from my TiVo to save space. I didn't think it would work to plug the external into the TiVo, but I tried, and got a message: This DVR does not support using USB to connect a device to add recording space. I don't want to add recording space (I already have the official 1TB extender), I just want to be able to watch the recordings on my 61" tv, rather than my 17" laptop monitor. I don't want to burn them to DVDs, as I have over 500GB of files, some of them over 30 gigs. I suppose I could convert them to another format, but that would be a huge waste of space and time. I use TVMobili with my Blu Ray, but it doesn't recognize .tivo files. Any suggestions?
