I have 2 TiVo's, 2 Slingbox, 2 wired computers, a wired blu-ray player, a wired Smasung SmartTV, a wired VoIP box for my home phone service, and a wireless access point on my home network serving a wifi printer, a tablet and a laptop. The little LinkSys router I have has only 4 network ports, so I picked up an unmanaged 8 port network switch to give me the extra ports I need connect everything. Recently, I'm having trouble transfering shows from a Premiere to a TiVo HD (Series 3). Works fine going from the HD to the Premiere, just not from the Premiere to the HD. Whenever I try to transfer a show from the HD to the Premiere, the Premiere will spontaneously reboot. It does that every time regardless of what show is selected or whether it was an HD recording or not, and show length doesn't appear to matter either. It's every transfer, every time, and only when going from the HD to the Premiere. I contacted support to try and figure out what the problem is (online chat). The support guy (Nathan) said that I'm on an unsupported network configuration, that network switches of any type aren't part of the approved network connection design and that he couldn't help me. <begin rant> TiVo technical folks need to start thinking about just how people use computers and things in their homes. NO ONE that I know (including my aging parents of all things) has less than 4 networked devices in their homes. If the only supported configuration is to have some generic router running the Internet connection and both (or more) TiVo's connected to it AND NOTHING ELSE, then you support people have a serious problem. Nobody, especially anyone that is tech savvy (at least those that I'm associated with), has a configuration like that. And besides, what the hell does my Internet router have to do with communication between 2 TiVo's on the same network?? The router doesn't touch internal traffic unless it is destined for the Internet link. Don't even try to tell me it does. I'm not only a Cisco and Microsoft certified IT tech, but I also manage a wide area network for an entity that covers several US states including the one I live in. I'm well aware that the TiVo's need to 'call home' on a regular basis for updates, guide listings and the like, but I can't for the life of me understand how that should have anything to do with transfering a show from one TiVo to another, especially when it worked fine the week before and just suddenly stopped working a week later. <end rant> I understand that TiVo can't provide support for people's home networks, regardless of the type or arrangement or what hardware is in use. That's not my problem. My problem is that TiVo Support will not troubleshoot an obvoius problem when a network switch is involved. That's just ludicrous. Now, having gotten all of that off my chest. Hopefully folks here can provide some insight into the problem. Tivo HD: 10.1.1.11 address (static) wired ethernet connection Tivo Premiere: 10.1.1.10 address (static) wired ethernet connection Transferring shows back and forth worked not more than a week ago (that's when we last did it). Yesterday afternoon it failed as described above. We tried 7 or 8 different show transfers, all failed as described above. I transfered 3 shows to the HD, all without a single issue. SO I know they are talking to each other on the network, it just appears that the Premiere is having a hard time with things. This is the third time in a couple years I've contacted Tivo Support for something, and I'm sorry to say its also the third time they've let me down. My last call was over a year ago concerning a dead Tivo box. Instead of fixing it ($150) we repalced it with a new Premiere ($99). I was told that the old dead box would be removed from my account. It's still there, and they still want me to pay for it or reactivate it even though it was not only unusable, but was dismantled and recycled more than a year ago. Before that, my first call, was for this same type of problem. Back then I was on a supported network configuration and they were still unable to help me. I actually found the answer here after asking for help. My wife is fed up with Tivo at this point, and she's about ready to pull the plug. We already own the hardware (and one lifetime activation) so I'd rather try and fix whatever the issue is first. But I could just as easily setup a couple XBMC boxes or Media Center or something and replace the Tivo's completely. I'm considering that, honestly, but we've already invested so much money in the Tivo hardware that I'm not ready to part with it quite yet. Geez, I'm long winded. I get like that when I'm upset.
