I tried searching for these topics but maybe I was not using the right terminology because I couldn't find any previous threads. Forgive me if these are repeats.
At this point, I have replicated almost all of my favorite TiVo features in the Channels DVR ecosystem. However, there are still two things I really miss, though I suspect they may be Apple limitations.
The main one is how, when fast forwarding at the 2x or 3x speeds, a TiVo will move the stop point back a few seconds when you stop fast forwarding so that you don't miss the beginning of the next show segment, or the next play if you're watching an NFL game. Is there any possibility that this could be possible in the Channels AppleTV app? Or, are things like FF/RW and function of tvOS? Commercial skipping doesn't always work, so being able to FF and then stop and have it tick back just enough so that you'd don't miss anything and/or have to manually RW was a pretty awesome TiVo feature. For football, I have slightly compensated by setting the FF interval to 7 seconds because tapping it 3 times is usually a reliable way to move from snap to snap without missing something.
The other feature I miss is when watching a recorded event and being able to play it back at 1.33x but having the player adjust the audio so it still sounds almost normal, and not Chipmunk-ish. This was another nice quality of life TiVo feature that I used a lot for soccer, when I could watch a recording of a 90 minute game in 60 minutes and have the audio sound not terrible.
I think Channels is amazing, and the community of add-ons makes it even more awesome, but after 25 years (starting with a DirecTiVo,) is was still a hard decision for me to decommission my TiVo Bolt (on its 3rd HD and still set to the original interface.)

Yeah I get that.
