I recently posted a nice review on the Tivo Stream4k however after a couple of days weird stuff started happening so I would caution anyone thinking of buying one to wait until they get the kinks out with some updates.
That said I realize the issues I am having could be limited to my equipment or the combination of my SONY TV sets and the Tivo Stream.
I finally disconnected the units after they kept trying to turn my TV sets on and off as well as force my TV set to the HDMI port the Tivo is connected to when I first turn on my TV sets.
I went into setting on the Tivo as well as my TV sets and my AV receivers to make sure everything was set properly. They were.
I thought it could be a communications issues with my AV receivers (Denon and Marantz) but this latest issues of forcing me to the HDMI port the Tivo is connected to tells me it has to be something happening with my SONY TV sets and the Tivo Stream.
This is unfortunate because otherwise it seems like a nice piece of equipment but not functional for me at this time.
Proceed with caution. Might work well for others but if anyone tries the Tivo Stream with a SONY TV I would be interested to know if it acts up or not.
Yep very common issue.
