Coby DVD-925 Theater System

I bought this on sale at Canadian Tire before Christmas. Thought it would be a great system. I knew I wasn't getting the best home theatre system but I thought that Coby would back up my purchase. I have had nothing but problems with the Coby DVD 958. The odd time it doesn't send signal out to the tv so I have to reset my tv input, when you turn it on the sound likes to choose its own volume, I turn it off at level 10 it turns back on at level 30, which really hurts the ears. Sometimes the sound level doesn't stay consistant either, sometimes when I watch a movie, I can have the level medium but other times with the same movie you have to turn it up loud to hear. Its not consistant.  The item doesn't have good sound, all I get is distortion when watching movies, tried to call tech support and it is non existant and even on their website, my model is no longer available.  Save the hassle and buy a good brand name, it will be worth the little extra you pay for it.
