It is junk. For good sound DO NOT BUY all in one systems, that goes for any one!!!! I looked up the unit, the amazon reviews of the Motorola DCP-501 are poor, not uncomine for all in one units.
If your on a budget get a Onkyo HTIB (range $350-$800) and then a cheap bluray player ($100) or a mid price DVD player $60-ish.
I had a phillips home theater system back in 2003 that was a 5.1 system with a powered subwoofer. The dvd player was built into the receiver and it started messing up--dvd's would start digitizing and ultimately stop playing. So, I replaced it with a Motorola DCP-501 (?). The philips receiver definitely had the surround sound going for it (it sounded like bullets were hitting the wall or that the dogs in the film were barking outside my front door). Since replacing the phillips receiver with the motorola it doesn't sound like this any more. Sound is coming through the surround speakers but it doesn't operate like it used to. I've read the manuals, turned up the volume, made sure that the motorola had the proper decoders, I even ran 16 gauge wire from the receiver to the surround speakers to see if the wires in the wall were faulty and I can see nothing wrong except that I am not getting the surround sound like I used to with the phillips. ????? I really didn't want to buy yet another system if I was missing something simple. What am I missing or doing wrong?
