It’s called using your knowledge and expertise, along with what the question is (in this case a DVD Burning problem), and deducing the meaning of the question and realizing the person could have made an error. This is sometimes referred to as “reading between the lines”. LOL
Since I use DVD Decrypter to burn ISO files also, this was a logical conclusion.
Since to me the name of the program really has no bearing on the fact that he is having a problem with a pop-up about locking the drive access ,I used my experience and knowledge to make this deduction. Common sense made the light go on that he more than likely meant DVD Decrypter which was proven out in his second post.
tom_mk, there must be another program trying to have access to the drive. Do you have a bitsetting program open or another program that loads with Windows open that could be trying to access the drive also ? You might want to do a Alt-Ctrl-Delete and see what processes are running in the background that may be trying to access the drive if any. Maybe turning off the auto-insert notification where Windows asks what you want to do with the blank disc when you insert it if you are using Windows OS which i assume you are since you are using DVd Decrypter ?
