Hi, Ive been using samsungs ht thx22 home cinema system for around a year and now its decided it wont play original dvd's any more!!. It has not had any hacks applied so i dont know why it started doing it. The strange thing is is that it will play copied dvd's no problem and work every time I have put a dvd lens cleaner though it but still no luck. So at the moment anytime i want to watch a original film i have to copy it first. Any idea what the problem could be. Thanks Simon.
