I have been using CloneDVD happily since it came out using my SONY DRX-500UL in Windows XP (latest patches and upgrades and firmware). I just bought Plextor 708UF and it also worked fine with CloneDVD till I installed Roxio EasyCD/DVD 6 that came with the plextor drive to use packet writing.
Every time I open CloneDVD and preview a movie the system crashes with a BSOD after few seconds (tried different movies). The CDR4_XP.SYS file installed by Roxio showed up on the BSOD so I uninstalled Roxio Easy CD/DVD and all is well again. I also have AnyDVD (latest version).
Is this a known issue? System is custom built on Supermicro X5DAE Dual Xeon 3.06 GHs board using an LSI Logic Megaraid 320U dual channel controller with four 15,000 RPM Seagate SCSI drives in RAID 10 configuration. Both Firewire DVD drives attached to an Adaptec AFW-4300A Host Adapter (PCI Firewire board).
