Magnadyne RV5090 DVD not working

[Skippy38]

I have the Magnadyne RV5090 installed from the factory. Everything works as it should except the DVD/CD player. First time I tried to load a DVD it worked great, now it will not load the disc. It just moves it in and out about 1/2" but will not load it. This unit got generally OK reviews, wondering if I can reset it somehow or am I stuck with no DVD/CD player?
