Disable anydvd for a second (exit the tray icon), does windows get to see the disc now? Decrypting titles (depending on how touch the encryption is) can take a few minutes. How long has the scanning been going on?
If Windows doesn't see the disc when exiting anydvd, then it's definitely not an anydvd problem. You've got 1 or both of the following.
- dirty and/or defective disc
- dirty and/or defective drive
If the drive sees other discs just fine, then it's option 1 and the disc is either dirty and/or defective. You could try a soft clean with sa microfibre cloth but if that doesn't work it's defective and you'll need to exchange it.
Exit anydvd first, THEN insert the disc. Not reverse. Can you see the disc in Windows explorer? Yes or no
