Also, there's a very short window for the Act II egg to push enter. If it's not working, rewind a bit and hit it right before or as the words are coming up on screen.

Thanks for the tips but I already tried all of those things.

With the Act II one I even went right back to slightly before and then pressed enter over and over again like a crazy person so that I'd be sure to hit it, and nothing. As for the numbers, I wasn't even pressing enter (I know you're meant to) - the first time I touched the numbers, it took me off somewhere else. Even pressing enter doesn't do anything for me, sadly.

Oh well. I found the extras using VLC on my laptop anyway!

tried on my cheap-a** dvd player-made one easter egg work. tried it on my mac laptop -- made two work. visited the family for the holiday, put it in parents slightly nicer but by no means spectacular dvd player -- easily got all three to work. Not sure why this would be, but my advice if you can't see these is find a better dvd player (my above-referenced one is part of one of those all in one shelf stereo systems)

Thanks everyone for the 3 you've found so far! So fun!
Another easter egg: Watch all of (or just skip to the end of) “The Music” featurette. When the Menu pops back up, “What Just Happened?” will be selected, press 6 then enter. Something will flash across the screen; all I can say is be afraid, be very afraid. It is very fast. I got a screencap of it tho, so if let me know if you want it.
I didn't find it: I credit DJ from the doctorhorrible.net fansite for finding this.

I got the same problem as you, Rach.

I got the Moist one to work (bloopers were lovely), but none of the others. I tried about 30 times for each, on my computer and my dvd player. I'm gonna have to resort to finding the files on my computer and playing them individually. DAMMIT JOSS!

Oh, and by the by, at the bottom of the DVD credits, it says "Commentary! The Musical by j, j, m & z (lyrics at drhorrible.com)"

So will the lyrics to "Commentary!", or just to "Dr. Horrible" be on the website?

I know you've solved your problem, but in case you were wondering, I was able to access the same easter egg by pressing pause on chapter 6 and hitting play twice.

During the FBI/ELE warning, what's up with the flash of Bad Horse's head with three eggs -- green, gray, and blue -- superimposed over him?

@Tamora,

The twitter page claimed that there would be lyrics for Commentary! The Musical posted soon, so I believe both will be available at drhorrible.com.

Perhaps as a hint to the three hidden Easter Eggs, each with differently colored countdown timers?

I can only get the Moist one, too. (I get the countdowns for the others, but number + enter kicks me back to the menu.) Can someone tell me how to find the files on a Mac?
