No. Just NO.Here's the thing. If it actually worked unobtrusively, and the tradeoff was autoskipping three 3+minute blocks of commercials in return for a 15 second at the beginning of a show, then maybe. BUT, that's not the device/experience and trade off that anyone made when purchasing existing products.
Personally I don't give a **** about 'autoskip'. I'm on TE3 and always planned to stay that way for unrelated reasons, and see no point in autoskip when I can skip with a single keypress (and have to manually do it via 30 second skips on most recordings anyway)
The idea that a preroll ad would be in any way acceptable, even your wishy-washy "maybe", as a tradeoff is moronic. They are relying on weak minded fools to say "well I'm avoiding a lot of ads with the Tivo, so I guess one little one won't kill me".
That's how it starts. Next they'll make that pre-roll ad not skippable, and give some made up reason like "only a few percent of customers were skipping them". Then they'll bring in ads that play anytime you pause, because the DVR isn't doing anything else at the time, right? Then they'll start accepting money from networks to make ads unskippable in certain programs, and tell us not to worry because "ads are still skippable in over 99% of programming".
