Query: Can't read my DVD-R discs...

I bought this DVD player because my old Zenith unit have difficulties reading the DVD's I burn on my computer. Sometimes, it skips some images and it is slow in the beginning of playback. I tought that a new unit with all the new technologies would help. Not at all !This DVD player can play all my commercial DVD's... but when I put any of my own DVD's, it only return me the message "C 13 70 - the disk is dirty"... even on a brand new burned DVD fresh out of my computer... At first, I tought that it was my burner... So I put my DVD in my neighbor player: no problems. I tried it in my old Zenith: no problem. I put it in the new Sony unit: "C 13 70..."Believe me, I'm a big Sony fan. My video cam is a Sony; my computer is a Sony; the burner in my computer is a Sony; my TV set is a Sony; even my telephone is a Sony... But all I could say is DON'T BUY THIS DVD PLAYER ! It is a big disapointment for me...
