My bush dvd won't read my reference manuel disk for my nikon camera?

I just bought a bush dvd player dp9301 and it won't play my reference manuel disk for my nikon camera

The Bush DVD player only plays the following file formats

Playback compatibility: DVD, DVD-R/RW, DVD+R/RW, MP3, WMA, JPEG AVCHD.

My guess is that the Nikon manual disk is in a different format, maybe one that needs to be read by Adobe Acrobat

It's a data disk meant to be read by a computer.
