I am running the latest version (22.214.171.124). Now, I have not been ripping any dvd's with this particular PC (it's a new build), so, perhaps all I need to do is reinstall? I am a fully registered, paid-up user of AnyDV But this problem is weird and I've never encountered it before. The dvd is "BBC Video: Planet Earth, disk #2, narrated by David Attenborough" IF the dvd is in the drive during boot-time, Windows XP will not boot at all. It gets stuck and freezes. IF I insert the dvd after Windows XP has booted, then AnyDVD says, "Scanning the disk...please wait" or something to that effect. However.... no info is shown in the status window for that drive. It says, "No disk inserted in drive E:". If I then try to navigate to the drive via Windows Explorer, then Windows Explorer crashes. I cannot even ctrl-alt-del and exit the process, because if I do that, Windows crashes and I have to hit the power button. If I run CloneDVD, it crashes and I cannot ctrl-alt-del and exit the process either. Instead, I have to hit the power button. This is weird and makes me think the dvd has some kind of software on it that interferes with Windows. It stops my Operating System cold.... any ideas? I am running Avast anti-virus, BitDefender Anti-virus, Data Execution Prevention, and I also regularly run Ad-Aware, so basically I highly doubt there is any trojan or virus on my PC as some have suggested in other threads. Also, as long as I don't have Planet Earth in the drive, I seem to be ok... Is this some kind of bad-a** copy protection ?
