trying to burn a dvd for my brother in law on an iMac G4 800mhz with a superdrive. using idvd 2 and i have updated the firmware. no other programs are running during the burn. i've made about 4 attempts now and each time the burn process hangs up when it gets to the end of stage 4. Burn process counts down from about 28 minutes. Eventually the progress bar shows 100% but says "about a minute remaining" and stays like this until i force quit. after force quiting, finder notices a blank dvd-r has been inserted and asks me what to do with it. seems weird that after idvd has written to the disc for 45 minutes there is apparently no data on it that the finder can see. anyone have this problem or know what might be causing it? big thanks.
