I'm with BAMCAT and others who feel that this enhanced content downloading is outrageous.
I ordered and pay for Tivo service that has two channels *always* recording. I like to watch two channels at once, switching between them at commercial breaks. I set up my tuners for the two channels I want to watch and then I find that DTV has taken over the channel I was not watching at the time and taken away the program that I was watching. And this happens so frequently in prime time!
As far as I am concerned, DTV is depriving me of the service that I pay for and expect. I would be in favor of a class action suit.
No Directv Tivo receiver has always had two channels recording 24/7 content for whatever channel you set. I know you might think so, but nope, never has happened.
They have always downloaded enhanced content on one of the tuners at some point, usually at around 2am.
If they aren't doing it at that time for you right now, then likely tivo screwed up and its trying to grab the content at the wrong times of day.
But good luck with your lawsuit against tivo, since they are the ones that are actually doing all the coding of these boxes and obviously cant get it to work right.
