Harman Kardon DVD50 5-Disc Progressive-Scan DVD Player
Great DVD Player with one exception...
I have owned this DVD player for several months now and have found only one flaw with the product.  If a DVD or CD disk is not properly loaded into the carousel tray or if a disk should vibrate from its position in the carousel, the tray will become jammed and cannot be automatically or manually opened.  Don't bother trying to take the cover off and fixing the unit yourself, because even after the dislodged disk is removed, the tray door will not automatically open when the button is pressed.  The entire unit will have to be serviced, which isn't cheap.  I understand that the trays are made in such a way to accommodate different formats, but this has led to the above problem.  I guess you take the good with the bad.  I do not recommend this unit if children will be operating the system, as it is too sensitive.
