I hv been using this dvd player since july2005, and to go by its performance I have not experenced any major dificulties in operating this system. Though there was some problem in reading few DVD disks of course of a pirated one, but was not such problem in reading the orginal or good quality discs. It though take quite a time in reading the mp3 discs but has not shown any problem in its audio or video quality. insted is been of a high or good. It still has few hitches that it is a 2.1 channel audio output. so you have purchanse a home theatre system with seperate 5.1 channel audio output amplifier. and player dosen’t have the volume option, and also the LED display could have been more attractive and display options.over all its a good value for money dvd player. and pls read the manul book before operating any player it could save from many troubles from bad operating
