Why can I copy a particular CD-i title?
In some circumstances it might be impossible to copy a particular CD-i title. This might have several reasons, but the two most common reasons are: • The discs is slightly ‘out of spec’. Due to some technical issues, the CD-Recording tool is unable to read the contents of the disc (for example the session is closed as CD-Audio instead of CD-i, so the CD-ROM drive does not return data the proper way). • The discs contains CD-Audio tracks. Especially CD-i’s with CD-Audio tracks can cause a lot of troubles when trying to copy them. There a two different methods of including CD-Audio tracks on a CD-i disc. The first is by adding CD-Audio tracks after the initial CD-i data track, the second is according to the CD-i Ready format (refer to What is CD-i Ready?). Especially the latter one is difficult to copy, since the CD-i data is included in the pre-gap (the pause sectors) preceeding audio track 1. This makes the CD-i data invisible to most CD-Audio players, since they usually skip the pause
