I was a beta tester for TiVo Stream, as well as the ‘Palms’ TiVo DVR software.The Stream shows promise, and I loved the remote; I just preferred the layout of Chrome w/android TV better (and have gotten used to their remote). If you pay for Sling with TiVo Stream, you will get some of the “download” DVR capabilities. I had purchased a Roku just before getting to try the TiVo Stream, the Roku is my least favorite by far (messy layout, and non-intuitive remote).
I hated the Palms menu version, it lost so many of the TiVo capabilities that the longtime TiVo owners love. I tried to like the Palms, but just couldn’t put up with it; then it took 3 months of emails and phone calls with customer service to be able to push a rollback software version to my TiVo so that I could even further rollback my TiVo to the previous version (Hydra)… and then, I had to reset my TiVo Roamio so that I could rollback to the Quattro version.
In my humble opinion, do *not* choose to upgrade your Menu version.
