I have a ZD7000A (ZD8000 motherboard), installed a Matshita UJ851S DVD RAM drive. Nothing but problems. Removed drive from system, reinstalled, removed upper and lower filters, tried different codecs. Nothing worked. Would get to the end of a burn and program stopped with errors. Tried different brands of DVD's. Was ready to buy another drive until I found the forum, link below, with a driver that had the drive check removed. It worked, my drive now rips, burns, and recognizes any dvd I put in it...
HP Pavilion ZD7000A
Pentium 4 3.2 Ghz Hyperthreading
