I can't seem to get my DVD's to "repeat" when on playback. Whenever I play a DVD, and by using the remote control, try to get the chapter/title to repeat, all I get on the screen is that horrible circle with a line through it! Am I missing something? This function works with other DVD's , both commercially and ones authored in Cyberlink's Power Director. I am using DVDA1c, Any suggestions would be welcomed.
