My reason for posting is to determine if I have a "faulty" NEC 2510A. My speculation is due to having both PS2 back ups and DVD movie back ups playing badly. My PS2 back ups seem to take FOREVER to load, most of the time freezing, and sometimes do not even respond. My DVD movies "tile out", freezing, and sometimes the audio and picture can not seem to catch up with each other. My media is Sony 1X-4X, my software is Nero 6.6 (sometimes Alcohol 120%), and DVD Shrink. Any suggestions??? BTW... I ALWAYS burn at the LOWEST possible speed (never exceeding 4X).
