I found this problem when I was doing the followiong: I open the "Add Movies" window in the advanced mode where you can edit all the details at once and read one movie files form a CD, save the details and press new to start a new movie, then I read another movie files form the CD and I noticed that the number of disc add up to what was before the second one so let's say that the first movie had 2 files and I read the second movie files which are 1 the number of disc in the textbox for the second movie will automaticly become 3 which is wrong. All of that happens only if I don't exit the "Add Movies" window and enter again...
Sorry if my explanation is not clear enough. Ready to answer any other qustions about this matter.
