Disc one (I haven't gotten to the other discs yet) begins with 4.5 minutes of ads (Sesame Workshop, Electric Company, Old School Vol. 1). That's bad enough (though not so uncommon); what makes it intolerable is that there is no way to skip over them. The ads have to play through every single time you load the disk. I press "menu"--not permitted. I press "top menu"--not permitted. I press "skip forward"--not permitted. The only thing left is fast forward, which takes less time than regular play but is still a lot more than I should have to put up with.
I thought about mentioning this in my review, but different. Yeah, it's annoying. I've seen that Sesame Workshop promo many times since 2004, and it is tiring to watch. I've already seen The Electric Company preview on the Super Mario Bros. Super Show, The Weird Al Show, and Sesame Street: Old School Volume 1 releases. But I'd never seen the Old School Volume 1 preview before. And at least it's only three previews, as opposed to five or more like on other DVDs.
And it's sort of like the previews on older video releases. Back in the early 1990s, most videos had nearly three or less previews, and by the late 1990s, there'd be many previews. Heck, I liked how most of the Jim Henson Video releases usually stuck to just previews for other Henson video releases (though the video release of The Muppet Christmas Carol had a preview for The Lion King, and some later JHV releases had previews for other Disney videos), but didn't like how the Jim Henson Home Entertainment releases had many advertisements for non-Henson videos (though there were plenty of such ads, but first we'd have to sit through several unrelated promos).
And it's good that all of the previews here are relevant to the set (yes, even The Electric Company, to an extent). Do the Electric Company DVDs have any sort of Sesame Workshop promos?
