For the first three months, the portable DVD player worked good. On the fourth month in the car, while hanging in it's headrest bag, the player would stop and a white screen apprears and movie doesn't re-start unless the power was shut off/turned on. It would re-play, but if a slight bump from road happens, it stops. Then at home, if the screen was slightly re-positioned, it would stop. When I called Mustek, the customer service was lousy, all he could say was these only had a 90 day warranty, and could not offer a repair suggestion. Luckily I opted for a extended warranty when I bought it from Office Depot, and the customer service person said this was a common problem with this system (ribbon defect from monitor to case), and he would send me a store credit card to buy something else, as he didn't know of a repair solution. So, now I will search again for a DVD player that has better quality.
