Hi ! I've been going through the stickys & FAQs to try & resolve my issue, but have some questions. Please bear with me. I have an ATAPI DVD W DH16W1P burner. It's brand-new & a replacement for a dead burner.As far a I know, the firmware (version No. LA11, according to AnyDVD) is the latest. I can find no information anywhere on the web as to who makes the burner or how to find an updated firmware. Recently,upon loading a disc & running AnyDVD (latest version 220.127.116.11) the program displays " no disc in drive". No changes have been made to the computer. Reboots & reloads make no difference. The same discs load fine in the same version of AnyDVD on my laptop. (Licensed version of software, used seperately on both machines) There are no logs I can send because Any DVD does not appear to detect the disc. The burner is about 6-7 weeks old & has been running AnyDVD with no issues up to now.:bang: Have checked my firewall settings & AnyDVD is an "allowed" source. Running Norton 360 ver 18.104.22.168. No difference with firewall and or/antivirus on or off. The advice on the stickys suggests I try & uninstall/reinstall AnyDVD & check the drive. With this in mind, I have a couple of questions... 1.If AnyDVD is uninstalled is there any way to export, save & reimport the CSS Key archive ? 2. Have noted the release of several beta AnyDVD releases this week. Would it be of any use to install the latest version (22.214.171.124, I believe) to see if this could resolve my issue? 3. Would you have any knowledge of this particular burner with regards to locating manufacturer & firmware? Any advice on my questions or suggestions I could try would be appreciated. Thanks for your patience ! Jim H. St.John's, Newfoundland-Canada The oldest city in North America!
