Kavan,
DVD Player 1.3 came on OS 9.0.0 CDs and later but was not available as a separate download. As I recall, you are running 9.2.2(?); as such (and if memory serves), you cannot boot to a 9.0 > 9.2.1 CD and custom install the DVD Player. You will get a message stating your installed software is newer than the CD.
However, you can download TomeViewer (a Classic utility) from VersionTracker and extract the necessary files from the CD. You will be booted in 9.x > load the CD > launch TomeViewer (no window appears, just use the menu bar) > File > Open > MacOS 9.x CD > Software Installers > System Software > MacOS 9.x > Installation Tome > Open.
These are the five items you need; once they have been expanded on your desktop, make a new folder named Apple DVD Player and place all the items in the folder (even the extensions), then place the folder in your Applications folder. Be sure to trash all items associated with Player 2.7.

Highlight each item (or shift-click all five) > go to the menu bar > Archive > Expand > select desktop and expand (one of the options here is to create a new folder for the items). Restart and test.
