Here's how I got mine to work
(I didn't try to apply any fixes or extract anything... I had tried the whole complicated process for the plainfiles torrent before, but I just ended up with a major hiccup at the layer break and a freeze):

-Downloaded the ISO torrent

-Used Nero Image Recorder to convert to NRG format

-Burned with Nero5 to Memorex DVD+R DL (that I bought online)

It's interesting though. The first copy I burned played perfectly on my win2k pc (PowerDVD5), and when I tested it on a few players at my library most of them weren't even recognized (JVC and Toshiba, iirc). They'd say "bad disc" or "wrong disc" after trying to read it for awhile. One of the players was region free and it still couldn't read the media. However the disc played perfectly on a region free Pioneer player (that was also incidentally hooked up to a laserdisc player). I also tested it on an XP machine with one of those crappy bare bones versions of PowerDVD and it played fine. No pauses at the layer break for the ones that worked.

Now I burned a second copy, using the same media, same image, and it hiccups badly at the layer break, for about 10 seconds and then freezes. You have to manually navigate past or skip the scene to move on. Really weird. And there were no errors when it converted and when it burned.

I have some friends I want to show this to, but unfortunately they have cheap players, so it might not work. I know in the past I've burned movies to show them and sometimes they work, sometimes they don't, even though I always use the same media. My sister has a laptop that sometimes isn't able to read commercial DVDs, even though she has the same PowerDVD software. I don't get it.

Is Dual Layer media just harder for players to recognize than DVD5's?

PS: The first "plainfiles" DVD9 I burned I did at 2.4x speed as someone recommended. Didn't make any difference. The others I burned (the one that was perfect and the one that wasn't) I burned at "max" speed.
