Ok, I have had a Tivo since 1999. And a S3 HD since 2007. The is my first time in the new interface. A list of things I don't like after a day. 1) Settings Interface - Not HD old interface 2) Signal Strength - doesn't work, the Tone sound stopped signalling me how strong the signal was, and all the signals strength were a lot lower, S3 were all 90+, this device not (at least this page doesn't report correctly) 3) The channel select page (I'm OTA) is old interface. And it really sucks! When I scan channels about 40 show up, but only 10-15 are good. So I have to remove all 25+ bad channels. I literally have to do two steps, step 1 get a pen an paper and channel surf - writing down the good channels. step 2 enter the channel select page and delete the bad channels. Why can't this page be in HD and show you video at the same time, so you don't have to switch back and forth and quality and/remove channels from your lineup. 4)Showcase apps- OLD!! SD! I never used this stuff in 14 years. Why does it have such a large button for something that UI doesn't match and I don't use. Let me remove it or remove it for everyone. Google discontinues OLD products, this should be discontinued. I don't want those GAMES. 5)Youtube, why is the Loading screen not HD? why does it take so long to load? 6) ****** Very annoying = takes 3 seconds to change channels!! Why do we have to see a black screen for so long! the s3 OTA channel change was instant, you didn't see a black screen.... ******VERY ANNOYING 7) Amazon Instant is CRAP, worthless, and OLD. come on.... this is not the amazon one app we want. I rather have zero amazon then this app that I have not used in 7 years with the Tivo S3. yet again it would be better to get rid of the old first. 8) ********another very annoying, when you switch between season pass page and live view, or tivo menu and live video - why does the video/audio flash off for a second. It is distracting and never happened on my S3. feels very broken and buggy. 9) new RF remote seems slightly unresponsive, every 100 button presses doesn't seem to register. 10) why is default 1080i and not 1080p? 11) tivo lanuch pad seems unresponsive and OLD, Fling queue is a non-supported google chromecast feature. why does the logo need to say "Launchpad for Tivo" shouldn't "Launchpad" be enough? maybe season pass page it should be called "Seasonpass for Tivo" and "Live View for Tivo" Each menu title should have "for Tivo" added to it so I don't forget what Device I am using. bad design.... 12) no Android support. I got the free Stream device. But I don't have or ever want a crappy iOS device. 13) NO UV MOVIES!! Booooo. we need Vude/Flixster ASAP **LAST ONE IS A HUGE CHANGE 14) When changing channels on the S3 Tivo had a temporary buffer for the other tuner (the channel you are not watching) would continued to recorded. So if you switched back to the channel you would still have a buffer. so you switch back and forth between two live shows (which are not being recorded on a schedule) and still rewind, the Tivo uses the opposite tuner each channel you change. But now as soon as you change the channel you lose your buffer!! Tivo is only using one tuner when changing channel? Why not do the same thing as on the old, use all tuners that are not being used and keep the buffers for the old previous stations, rotate them out so you would have 4 - 30 minute buffers. good stuff 1) hd OTA signal strength seems as good as my S3, even tho the testing page doesnt work 2) Slide remote works perfectly - will use this instead of the RF remote. 3) thank you for letting me hide how much drive space is used on the main window. seeing %10 used or 50% used is just useless, in 14 years of having a tivo I have never cared or ran not of space. 4) 4 TUNNERS!!! SO MUCH BETTER THAN 2 !! 5) Tivo MINI!! 6) Android App now works! with the S3 it was crippled. (however the setup was rather silly.. I could of designed a much quicker. 7) The physical box is REALLY small! I like. (I turned of the LED lights tho & miss my clock and LED screen that indicated what shows are being recorded.) all in all it seems like this unit is not completely new. it still has OLD interfaces and OLD apps Tivo really should of purged all the old stuff. I can't believe some of the choices they made in this software. But you have to remember. Tivo makes money from lawsuits, not US! Overall I think Tivo just have bad software designers. They can't seem to get away from OLD code. They have a business department that decides UI and makes bad choices. They should look at both the Roku and cromecast, both of those products are more innovative. They should learn agile programming and more software updates. knowing tivo this software will not be changed for another 9 months. and if you were agile, most of the bugs I mentioned could be fixed in days or weeks. But I love my tivo, because it lets me skip commercials and never miss a TV show. Lets me not have to pay for cable for over 9 years.
