Bug with coptToDvd?

Hi, I am a new user to CopyToDvD and I have encountered some problems

I tried to burn something into my CDs but the there’s nothing on the CD when I tried to view it with windows explorer. Is this a bug??

By the way, I am using NERO as well. Is there a conflict between these two softwares?

Another question that I would I like to put forward is : Is there a built in data verification in CopyToDvd to check that whether the data I have burnt in the CD are not corrupted?

Thanks a lot.
