Hello! I previosly posted in the german clonedvd forum, but no one can really help me. May here has some one an idea to help me. Im sorry for my english, whats not really good. I've got the problem, that my whole system freezes, when CloneDVD is transcoding. Only the reset-button can help. There is no differece where the sources are, dvd-files on the hdd or an original DVD. When i try to shrink these files CloneDVD starts to transcode and after a while: freeze In the german forum the only feetback is, that this must be a termal problem. But the mainborad temperature is about 30°C and the CPU is between 30°C and 40°C. Nothing to see about termal problems... My system: Core2Quad Q6600 at ASUS P5E3 Deluxe with 2GB DDR3-Corsair-CM3X1024-1600C7DHX-RAM HDD: Seagate ST3750640AS and ST3500630AS DVD: Plextor PX-130A and PX-810SA operating system: Windows Vista Ultimate 32bit with SP1 Does some one know, what the problem could be? Intel give for the Intel Matrix Storage Manager v18.104.22.1682 a known issue for Windows Vista "Intel® Matrix Storage Console may stop responding during heavy I/O operations". Can this be the problem? My SATA-Bus works not as a RAID but at AHCI-mode.
