Query: Magnavox MDV530VR combo DVD/VCR

DO NOT BUY THIS! I purchased this unit and was pleased for 3 and half months. The dvd unit ceased to work after just four months. Ironically, the full warranty is for 90 days only. I contacted Magnavox (Philips) customer service and they told me to eject the DVD and start again. Of course I had already done this and told them. They then said my unit was indeed malfunctioning and I could obtain a replacement unit for [full price]. ... If the replacement unit after just four months is priced as full price, it is obvious Magnavox/Philips expects it to last approx. four months. For this price, you'd be better off renting a unit!
