I may have spoke too soon. It seems that the player stops playing (remote screen in web applet goes blank) - I think it's going into standby mode - after about 34 minutes of playing. I can't find any settings with this time value in them, and this only happens when the screen blanker is active, whether it's set to blank screen or power off.
If there's anything else you need to know, please tell me. Would a savearea dump help? If so, which page(s)?
Thanks.,
Jason
