Query: System sounds great - until it breaks

I just got this system and the sound quality really is great, especially for the price. Its one of the few systems in this price range to have digital optical input, which is necessary if you're connecting certain components for dolby digital suround like an x-box. Although there is a setting called "Prologic", I'm not sure that it actually has a prologic decoder since the manual only says that it gives out prologic sound if hooked up to a prologic receiver. I'm only giving it four rather than five stars because I've noticed that sometimes it will read no disc when there is a disc there so it has to be ejected and restarted. Otherwise, its really a nice system.Update- 11/29/04- My system died like many other reviewers. Can't recommend for that reason.
