TiVo Bolt Horrible playback and reception

A TV only has a single tuner, while the Bolt has 4 tuners to record from. It is not being restricted, but its like its split into 4 signals for each of the 4 tuners.

 

Correct. You are not being restricted to 72. You need to check your SNR on your tivo. That will tell you if you are having signal problems. You may need a pre amp

 

Or maybe they're already amp'd and the signal is too hot. What about trying a 2-way or greater splitter before the BOLT's input to attenuate the signal?

 

SNR is considered a little low. SNR = Signal to noise ratio.

Tivo does not come with a signal booster. Tivo splits the signal internally to each of the tuners. Can you try without that booster connected?

 

The bolt on its own does not come with a signal booster. Not sure where that booster came from 27 is a little on the fringe for the SNR and you will see breakups when it drops below 25

 

I think you are referring to a pre amp that comes with the antenna. The tivo does not come its a booster

I would try the antenna straight connected to the bolt. No splitters at all which it sounds like you have there. You may need a distribution amp

 

And if you find routing the antenna directly into the BOLT gets your signal strength and SNR into a workable range, know that you don't need your raw antenna signal routed over to that other TV... since you could, instead, put a TiVo Mini there and provide that TV with a nearly identical experience to what you'll have at the main DVR.

 

The "restrictor" is call AGC. All basic Roamio and Bolt units use it. You are viewing System Information. A different view is checking Settings & Messages, Channel Settings, Signal Strength. This shows the actual signal and you can watch it settle at 72% as AGC kicks in. If your signal is over 72, then the AGC circuit has maxed out and your signal can get too strong. For OTA, SNR is good enough when your picture is good enough. I've seen postings with SNR numbers that vary greatly. With cable not so much.

 

Try adjusting the antenna

 

It is also possible your Bolt has bad tuners. It is rare, but I've seen some people with bad tuners recently, but those were Bolt+ units.

 

See if this post is relevant to your Bolt

Did I get a bad Bolt+ - terrible signal strength and SNR

 

Are all the Tuners on the same channel? The way to do that is tune to one channel on LiveTV, then reboot.

If those are all the same channel, there is probably hardware issue with your tuner and you should get the unit replaced.

 

Do what @sfhub suggested. Also, a basic Roamio and a Bolt do not display RS Corrected errors. File that away.
