I am a new iMac user, as well as user of Titanium 11. I have burned 4 iMovie projects to DVD. It's easy, quick! However, in all four cases, The DVD plays on my older Sony Blue-Ray player, but not on my newer Panasonic Blue Ray. I am creating either 1080P or 720p files, as I want these DVDs to play in a variety of players. I have tested my DVDs with friends' players and they work. It's just this one Panasonic Player that won't recognize the DVD. Is it, perhaps, looking for a menu thumbnail? If so, how do I create one? My DVDs are set up to auto play, as I couldn't figure out how to create a thumbnail "start" icon . 2nd issue: Why is the burning default PAL and not NTSC? Can I set it to default to NTSC (American Standard). This is a minor issue, but irritating to have to ask it NOT to convert to PAL each time I burn a project. Any help is appreciated. I'm not technical, but very application oriented.
