I have a Samsung DVD writer that appears to function fine, writes DVDs and CDs no problem. I'm in the process of backing up a lot of .avi files that are filling up my hard disk. The problem is that the new DVDs work fine for a day or so then cant read. I get some "cyclic redundancy check" error and it wont read or copy the files, even though it reads the disc and displays the contents in explorer.

Anyone else had this? Is the burner bad or the DVDs? They're Princo 1-4X 4.7GB DVD-Rs.
