I recently purchased the LITE-ON LDW-411S burner to back-up my collection of movies. But all the Movies which I have copied either freeze, or I get a disk error about 2/3 of the way through. I checked with LITE-ON and it appears that they are known issues with the 411s and –r media. So I followed their advice and upgraded the firmware, which did improve things slightly, but still no success. My DVD’s play great for the first 2/3 then I get a bad disk error. Trying various –r media and different burning speeds makes no difference. So I’m down to two options, try and find some +r media which works with the 411s, or bite the bullet and spend another £100.00 to buy the PIONEER DVD-R/-RW/+R/+RW IDE " DVR-106 " which I have heard good things about. So this is my last chance to save my money! Can anyone tell me any –r /+r media which works with the Lite-on?
