samsung is now earning bad reputation with tray mechanism of all kinds of their optical drives which usually fail sometime after their warranty period and company is doing nothing to rectify it.i have two such drives and don't trust samsung drives anymore.
I have long back stopped trusting these Koreans - samsung and LG.
All there products rattle once warranty is ovr - be it cd drives, TVs, Microwaves or ACs- ACs specially.
the final conclusion which i have forged out is you can get an seven inch high screen resolution portable dvd player in which all the above stuff is included along with a & inch portable quiet good screen as a bonus and more u have to pay is six to seven hundreed bucks ...so i dont think its worth the money ......
