Hi. I just burned my first DVD on my new Mac Pro. Edited with iMovieHD, then exported to iDVD6, encoded and burned (as a movie, not as data) with the Best Quality setting. The finished product plays perfectly in my computer drive, but when I put it in my Toshiba DVD player, it refuses to load. In fact, it locks the player up so badly that I had to unplug it, then hold the eject button as I plugged it back in just to get the disc out. The disc is a 16x Verbatim DataLifePlus DVD-R single layer. I made two copies, and it happened with both. My Toshiba player is compatible with both plusR and minusR media, and has no problem playing discs (plus and minus) that other people have burned for me. Is there something special that has to be done during the encoding/burning process to make discs playable in consumer players? If I'm going to be producing video discs for clients, I need to make sure that I do it in a way that maximizes compatibility with the broadest range of consumer players. Thanks for you help!
