Tivo has always allowed tweaks like this. Television is self destructing though. It is fascinating to watch the way it is falling apart.
Networks think they can gain share by pushing their popular shows into odd time slots, which impinge on viewers being able to change channels.
They went from the small "bug" in the lower right corner of the screen to animated "bugs" to ones that filled the bottom quarter and now to ones that fill more than half the screen.
The cuts in movies have become ridiculous. It started long ago with the fart scene being cut from "Blazing Saddles" and has gone into serious content clipping.
The percentage of time in commercial break has become almost HALF the program time in some situations. Anyone watching live no longer has any reason to continue to sit and watch.
We DUMPED Directv after many years and picked up the lowest cost Dish (only because we are in the boonies in tornado country) and went with Netflix and downloading stuff off the net. It was simply becoming TOO irritating to try to watch Directv, and the bulk of the programming was either repeat, infomercial, or junk. We aren't alone, the stats are showing mass migrations away from cable and sat service.
