First they gave us a PIP many of us do not want, and wish we could turn off.
Somewhere along the line they goobered things up so much that there is enough delay in moving from one screen to another that you can hear the final score of discover who the killer is from your PIP just in the time you are waiting for it to become mutable or pausable.
Next, they made shuttle controls useless when in PIP, which means you can't pause it to shut it up.
My workaround has always been to park the DVR on a channel that I don't get. That works well, at least until all tuners are in use.
Then they made it so you can't add a channel you dont get to "pick nine", making it that much more difficult to get to a channel that is quiet and has no picture (a channel I don't get).
But now they've gone too far; the latest uprev seems to automatically go to some other channel you do get even if you were parked on a channel you don't get when you began to watch a recording. The end result of that is that every time I delete a program I am done watching, I am treated to the video and audio of something I do not want to be watching or hearing, which could not be more annoying.
Nice Freak-ing job. DTV programmers seem to be solving problems we don't have in lieu of not solving problems we do have, by creating new problems. They tinker with stuff that does not matter that they understand but never have the ability to tackle the real ongoing problems that do matter, which they do not understand. They add features we don't want at the expense of the speed and reliability we do want. A company run by idiots that only employs idiots.
Ferchrissake, how difficult is it to make PIP a user pref, so that those of us who abhor it do not have to deal with it?
