Don't see this reported anywhere, so forgive me if it is a duplication. There is a small bug when swopping games in a certain way; try this... Boot up any DVD-R. Let it run for a minute or so. Press eject, insert new game, press eject to close tray, and *only then* press reset; the game will not boot until you reset it again. This is not really a big deal, just a small bug, but it would be nice to have a fix. For 100% success on swopping games, I press reset *first* and *then* eject the tray to swop the disc.
