I have got an odd DVD burning problem. I burn the DVD and can read it on the PC on which I create it, but when I try and read it on my laptop, it works fine as long as I dont let the disk spin down. If I leave it for about a minute or so, it just becomes unreadable. I can however ejected it and reinsert it and everything is back to normal. What the hell is going on? Any suggestions on what it might be? For the record, my burner is a RICOH 512 and the computer I am trying to read it on is an packard bell iPower with a Mat****a UJDA730 DVD/CDRW drive.
