Need advice.. I have purchased and backed up many DVDs but have come across a problem with some recent disk I purchased from Meritline. With their 2x dvd-r disks...or atleast this package of disks... everything goes according to plan..till the end.. when Nero pops up with failure to write... and it is at the Lead out faze. After this happening several times I made arrangements to return and have them replaced. but last night tried them out on my player.. and all seems to work fine... movie, extras I already got burned by a batch of Ritek I received from them... that failed 3/4 the way through burning.. but had prepurchased them before needing them and the time factor for returns was past due. There were 25 disks that were wasted. My question is has anyone come across the Lead Out error...and it still work or do you feel these disks are also defective???? Thank you for your input before hand... 50 disks are not cheap just to sit around.
