Hi Home movies that I have burnt on iDVD and Disc Ultilty do not work anymore on my emac (10.4.8). I get a message saying "Supported Disc Not Available." These are home movies made in iMovie and not copies of shop bought dvd's. I have tried changing the NTSC and PAL settings on iDVD and iMovie, but this doesn't seem to fix anything. I am able to play the movies perfectly on my TV and on my work mac book. This is a fairly new thing and it never happened in the past. I have already loaded the ilife 05 disc to see if it fixed any glitches, but it is the same. Any suggestions would be greatly received.
