"Medium Changed" Error?

[VCDBurner666]

Can someone PLEASE help me? I keep getting a "Medium Changed" error during the simulation process (I have gotten this once before during burn process as well while burning another VCD...needless to say my cd-r was ruined and unusable). Once I also got "Invalid Block Address" during this VCD session, But I have gotten "Medium Changed" twice now. I do not understand this as I have not changed the cd-r. At least I think thats what it means when it says "Medium Changed". Can someone help me with this.
I am using Nero Burning Rom to make the VCD.
I encoded the videos on the VCD with Tmpge.

Can somone please answer this post? I have tried burning the same VCD project three times since I have posted this and now I just keep getting the error "Invalid Block Address". What should I do?

I also have had this problem using Nero. There is nothing listed on the board that helps with this problem, but I discovered that if I use Nero Express instead of just Nero everything burns without the "Medium changed" error. Try and see if it works for you.
