I bought an "all in one" Panasonic home theater system (ie receiver, stereo and DVD are all one unit, not separate components) 5 years ago. Recently the DVD player refuses to play certain commercial disks I get from Netflix or Best Buy–it simply refuses to "spin" and says "Disc Error–No Play." The only fix I’ve been able to discover is that if I play an older movie in its entirety, after the older movie is over, the player will SOMETIMES load the newer movie (Its bizarre–its like the DVD player needs to "warm up" on the older disks first). I’ve tried a disc cleaner to no avail. Anyone have a solution? Alternatively, since the audio still works great (if I can get a disc to actually play), I was wondering if I could buy a new DVD player and somehow connect it to the current home theater system so I still have surround sound without having to buy a whole new system. Is this possible or do I have to buy a whole new system?
