I haven't actually popped in the DVD yet, but by looking on the inside cover (which still shows little screenshots of the cartoons) I'm assuming that "Pom-Pom Too" is Isle of Pom. Judging also by these screenshots, the Old Intros are all here too. However, this shouldn't be all to go on, as the little shots also (oddly) have pictures of Strongest Man in the World and Weclome Back. Not only did the site clearly say all Big Toons "up to 2005" were on there, they're not listed with the rest of the Big Toons. (Then again, Li'l Brudder and Experimental Film went unlisted too, but either way.)
EDIT--They're not on there. As if you couldn't'a figured it out by now.
I am about to watch it, though!
Also included is a "Cheat Commandos game", as the back cover says, which is apparantly titled "Blue Laserdisc Challenge".
EDIT: I'll go through a few things.
*SPOILERTASTIC, obviously.*
Coach Z appears in the opening thing with the DVD piracy warning thing or whatever. It's awesome.
"Why Come Only One Girl?" is about other attempts to make a second female character, featuring the UNNAMED GIRL FROM DANCIN' BUBS!!! And features some unused footage of abandoned cartoons. It's pretty hilarious.
"Halloween Awards Show" is cool--they apparantly forgot it was unfinished until "a few days ago". It's the conclusion to the "vote for your favorite costume!!!" thing from House that Gave Sucky Treats.
"Flash Forward", as you might've guessed, is the short from the Flash Forward conference.
"Pay Plus!" has you select everything thing with the remote--although it changes pages on its own eventually. You have the option to change which page is up at any time, so you can go back and forth if you weren't done.
The Original Book thing is a corny reading of the book. Same thing for "Where My Hat Is At?" They make fun of the "Coach Zee" spelling, too.
The syncing on Marshmallow's Last Stand, like...DIES when Strong Bad gets the bomb out of the stage. The part where "The Good, The Bad and The Ugly" is cut out for new audio, similar to how they changed The Cheat playing Happy Birthday (It is still in there during the commentary though, and the sound's okay there too). On the plus side, the commentary is hilarious.
Speaking of commentaries, the following I've watched have commentary:
-Marshmallow's Last Stand
-SNES Theme Song
-Where My Hat Is At?
-Original Book
-Cheat Commandos
-Cheat Commandos...Os
-Shopping For Danger (Featuring the lead singer of Y-O-U)
-Commandos in the Classroom
-Under Construction
-Happy Fireworks!
-Some Stupid Turkey
-Senorial Day
-Fall Float Parade
-King of Town (olde. And not the Strong Bad commentary, which is still there. New version has nothin'.)
-Yello Dello (old version here, too.)
-A Jorb Well Done
-The Luau
-Parsnips A-plenty
-Strong Bad Is In Jail Cartoon
-Bug-in-Mouth Disease
-A Folky Tale
-Homestarloween Party
-Pumpkin Carve-nival
-Malloween Commercial
-That A Ghost
-Halloween Fairstival
-The Best Decemberween Ever
-A Decemberween Pageant
-Decemberween Sweet Cuppin' Cakes
-Homestar Presents: Presents
AND THAT'S ALL, FOLKS.
Blue Laserdisc Challenge seems to intentionally be made to annoy you
The easter egg audio cuts in at the end of Shopping For Danger, before the easter egg can even be popped on. Something makes me think a few parts of this DVD were thrown together a bit...hastily. Just this and Marshmallow's Last Stand, though.
KoT cartoon has everything intact--The Answering Machine thing is seperate, though, and as far as I can tell the only part of the April Fools thing in there is the KoT version of the opening. Also, in the new version of it, they added in a...creepy voice for the little chef guy.
The storyboards have commentary automatically on, as you may expect. They mention Steve Irwin due to the bad impression of him they made in Yello Dello. I can't wait to hear if they get hate mail for being sarcastic about it OH GOD SUCH DISRESPECT. They also mentioned South Park doing the same Pitfall joke!!
There's a bunch of weird angle switches in the Reddest Raddish--I think they were in there to begin with though.
Homsar is only an easter egg in "House That Gave Sucky Treats", as far as I can tell--you get the pumpkin going down or up from the menu. In Sucky Treats, Homestar oddly does his little bit about going to your house before the title stuff comes up. In any other case he comes up automatically. Stinkoman turns up in the Funjob easter egg in a similar fashion to how Homsar is found in Sucky Treats.
The little dialogues the characters have from clicking on them in Halloween cartoons come up automatically at the end, except for extra scenes (like Super Kingio Bros., and assumably Strong Bad at the comedy club),
