I don't even understand why they released this at all. All they needed to do was make an app that turns your
android tv, roku, Apple TV into a mini. They could have just released that to the various play stores and charged for it. Why make hardware? Most people already have a streamer box of choice. I have a shield and it's awesome. Why would I buy this android tv device from tivo? It makes no sense.
To keep their brand relevant and capitalize on one of their best aspects... their remote. (although this particular version isn't that great)
Also releasing an app that acts like a Mini wouldn't work as well as you'd think. TiVos record the raw input stream from your cable company, which in a lot of cases isn't compatible with most streaming hardware. Most streaming devices can't decode interlaced video, MPEG-2 video or even MP2 audio without resorting to software decoders which, for anyone that's ever used VLC on a streaming stick knows, can be hit and miss. To maximize compatibility they'd need to use the transcoder like they do mobile streaming. The problem there is that it's not very reliable and doesn't provide the best user experience. Anyone that uses the streaming app can tell you that it's not the best user experience and not really ideal for heavy use.
Although I think there is still a possibility they could release an app like this for Android TV. Perhaps not Apple or Roku, but maybe for this new device. It wont work that great, and a lot of people will probably complain about it, but I still think there is a possibility we'll see this eventually. Although I wouldn't hold my breath.
