Hi,

I got a LiteOn 5001 DVD recorder. It got heat problem, so I rmaed it for installation of a fan. After I got the unit back, DVD recording and playback showed pretty bad pixalization. (commercial and DVDR). The picture on TV looked fine when recording. But the recorded DVD showed pixalization on both 5001 and another player. What could be the reason for pixalization? I hooked the drive to pc and there were no reading error. Thanks!
