OK well i've just finished testing both the PAL & NTSC versions on the HD-XE1 HD-DVD(the Uk version of the XA2) player. both played fine without any problems. So it has to be a bug with the Firmware on the NTSC only players. I also tested it on a very old Bush DVD player that has always choked at the slightest problem on a DVD and again the NTSC played fine. Someone has pointed out that when loaded into DVDREMAKE it shows some errors. well i have checked this and although that program reports the errors they are just remote button commands, present on both the PAL & NTSC, but these would have no impact on the playback of the DVD. My guess after all this is that its just the TOSHIBA HD_DVD NTSC players that just don't like Procoder encoded mpegs due to their firmware. If you do a google search you will see threads stating that their players did the same with some retail HD-DVDs before an updated firmware. Same freezing issues mentioned here. Good luck with ever getting a fixed firmware now Toshiba have dropped out of the HD-DVD market though. And it definitely does seem localised to just the Toshiba NTSC players. Seems like the XBOX360 HD-DVD drives play it fine. Also it has been mentioned that the trivia track disappears on the NTSC when skipping chapters. has anyone else had this problem? I tested it on the PS3 & my Panasonic DVD-recorder and i can't see a problem.

Well i'm half way through the isolated score track for the DVD-9's. Originally i was going to remix the track into 5.1 but its now looking like it will just be stereo due to disc space.
