I have a BDP7600 and normally it works even if it becomes quite hot while it is used. I sometimes make DVDs with the DVDstyler software. If I make a menu with several titles BDP7600 fails to start any title. After that it becomes completely locked and the only way to turn it off is to unplug the power. If I put the same DVD into a Toshiba DVD player I have it works without a problem. I hope someone has any idea about what to do. Thanks.
