I'm trying to burn movies with my Lite-On LDW-811S, but I'm gettting a coaster everytime! I have a P4 2.8Ghz with Via chipset and using DVDShrink to burn backup copies of my DVD movies. I'm using Ritek 4x DVD-R. After burning, I'm viewing it on my DVD player and I'm getting pixelated screen and the audio studders. But when I'm playing it back on my computer, everything is fine. I just flashed the burner with the latest firmware, HS0Q. I've gotten 3 coasters so far! The thing is, I burn the exact same DVD using the exact same media on my other computer, P4 2.4Ghz with Intel chipset and Lite-On LDW-411S, and I'm not getting any problems. Is there something up with my Lite-On LDW-811S?? Should I return it and get the slower LDW-411S? Any help will be greatly appreciated! I feel like I just wasted $80 on the burner! I got the Lite-On LDW-811S from newegg.com, retail packaging.
