I used my Samsung CDOM Drive SH-S182D to play a DVD disc. The playback is really jerky and the audio is broken. The strange thing is that the playback is very smooth using another BenQ CDROM drive housed in the same PC.
I probably been having this problem for very long time. The disc copying speed between my 2 CDROM drives in the same PC has been very very slow. I finally found a solution from http://club.cdfreaks.com/showthread.php?t=205247 . It was because the SH-S182D is stuck at PIO mode. I follow the instructions to uninstall the highlighted controller in my PC. I rebooted my PC, the playback on both drives are very good now.
