Just to follow up, the menu trick does work to bypass the region coding. I watched Runaway Train last night. When the screen comes up that says "This disc is not playable in your region", just press STOP, then POP-UP MENU / TOP MENU. It'll take you right to the blu-ray's main menu. Watched the movie, all extras, everything worked perfectly. I haven't watched the Spider Baby disc yet, but it supposedly works on that one too.
The only catch is that it would not work on my Sony player with Wi-Fi. Since it's connected to the internet, when you press stop it brings up all these options for NetFlix, YouTube, Hulu, etc, so it isn't focused solely on the disc. But if you have a player where you press STOP and it just brings up the company logo or a blu-ray logo, then it should work.
