We've started our 30 day trial of our new TiVo Bolt+ and 3 Minis - as a possible replacement for WMC 8.1 and our Xbox 360 extenders, and will post a more thorough review when we've completed the evaluation.
The commercial skipping works very well, compared to WMC. While we had WMC configured to automatically skip commercials, with the TiVo (for the prime time programs on the popular channels), we have to hit a button on the remote to skip over the commercials. And, the commercials are marked within minutes after a program completes airing. While we'll miss the automatic skipping, having to use on button on the remote to skip isn't bad - and still much easier than having to manually skip over a block of commercials.
The Bolt and Mini boxes do not have an off/standby button. This means once you start using one of them, a tuner is allocated per active device - and will keep using that tuner for several hours. The TiVo software will steal a tuner, if it needs it for a higher priority activity - but this feature does mean the Bolt will have tuners busy for inactive devices and making temporary recordings for the live TV buffering. While it is possible to force the boxes to go into "standby" mode by a sequence of 5 button presses, that only turns off the display and doesn't appear to free up the tuner. Will have to do more testing on this when we get all 3 Minis installed - and see how well this works when the Bolt+ runs out of tuners.
The Bolt's "Quick Mode" works better than WMC - allowing you to watch a program at 1.3x speed with audio. It's enabled once by pressing the "Play" button and then "Select" - and stays enabled for the rest of the program. With WMC, the "quick mode" gets disabled every time you do a commercial skip - and has to be re-enabled.
The TiVo recording management is different than WMC - with their "OnePass" feature - for some reason, when I set up the first recording rules - it wasn't recording any of the programs - but after I deleted those and entered them a second time, they seem to be working correctly. We immediately turned of the Suggested Recordings feature, since we only want to record the programs we pick - not extra episodes/programs we don't intend to watch.
Integration of Netflix, Amazon Prime, VuDu, Plex and Xfinity's On Demand is pretty good. With Plex, was able to watch programs previously recorded on our WMC box, plus downloaded/personal videos along with viewing pictures and playing music. With the other streaming services, we're able to watch 4K programs without having to load up the TV's smart apps. Plus, TiVo's search searches the program database combined across Xfinity and all of the streaming services (giving you the option of which service to use to watch a program). The only negative is that browsing for Xfinity's On Demand is not as nice as the X1 DVR service, but that's probably not going to be a major problem.
TiVo's Android app is a significant improvement over the combination of Remote Potato and Plex that we have been using to watch live and recorded TV on our devices at and away from home. We were never able to get Remote Potato to work reliably on live TV. With the TiVo app, it automatically sets up a recording of the live TV program and begins streaming that program to your mobile device - even when we're away from home. This is something that the Xfinity app will not do outside of the home, except for a few of the channels that have streaming services. The live TV feature will be very useful to watch live sports programs when we're not at home or travelling. The major negative of the Android app is that it restricts downloading to the device's built-in storage and doesn't allow use of the SD card (which always has much more room), so it looks like we'll probably use Plex for downloading and have to get software working to copy the TiVo programs to our PC running the Plex server - when we want to watch programs offline (like on an airplane or in a hotel, without a high speed or reliable network).
While we're used to the WMC environment - and it has worked well for many years, at least our initial impression of the TiVo Bolt+ is pretty positive.
Our plan is to use it for 3 weeks - and then make a GO/NO-GO decision about keeping it and permanently moving off our WMC PC and Xbox hardware.
Would still prefer to have more control over our DVR environment - and if WMC was still being developed & supported or either SD's DVR or Plex's DVR were clearly on a path to provide functionality comparable to WMC, we would likely have waited longer to make this decision. But, unfortunately neither SD or Plex appears close to having enough functionality for us to seriously consider...
