powerpc – Software restore on iBook G4 A1134

I recently bought an iBook and OS 10.3.3 iBook recovery discs. I have inserted the disc to restore the iBook but after booting with the disc inserted the screen in just black. There has been no dialogue to, for example, start the system restore. I have no experience with apple products of this age. Is this the usual experience? Is something going wrong? It has been like this for probably half an hour at least. I inserted the disc while logged in and started the Install OS X programme which restarted the computer. I had previously inserted the disc and help the C key to start it but encountered the same thing.
