For Project:M 2.1 related questions I would personally either ask the Toaster Bros, Shanus, Shadic, or JCaesar on Smashmods.com or Smashboards.com. Probably the best way to get a hold of them. Or get ahold of them during when they stream. Or go via the PMBR IRC chat.

That second delay might be the 1 frame delay they have been talking about. My best guess would be Re-install the demov2.1 again. Defrag your SD card. And make sure its its a 2gig SD card. thats If your using Gecko OS. Again that's my best guess if your having issues with it.
