[Resolved]  Philips — Deficiency in service

I have Sony Home theatre DZ 370. I saw the features of Philips hometheatre HTS 3571. It seemed that there are few good features than sony. I wanted to buy. Before buying I have deliberated a lot as philips service is very bad. Still on 12/12/2009 I have purchased the same. As expected their service is worst. Though the retailer informed Philips about the purchase, till date nobody from philips visited for installing the same. Therefore, I had to instal it. I have a DVD “Bourne Supremacy” which was purchased in Landmark at Chennai plays in sony. But it is not playing in the Philips Home theatre now I have purchased. I have purchased two more DVDs “Hotel Rwanda” and “Jackal”. Hotel Rwanda plays in Philips but Jackal is not playing. However, both the DVDs play in Sony. Why it is so. Even the DVDs purchased in Chennai do not work Why they sell such a system? What is the remedy.
