Page 1 of Dansai 852 - Digest?

I have seen someone quoting that with this drive you can put a variety of files, eg wav, jpg, mpg, vob, on a cd, hit the digest button which is the "intro" button on the control I beleive, and you will be able to play any of these files. I cannot see how to do this.
I can see mpg and vob files ok on a normal iso cd, but not jpg or wav. To see jpg I have to burn a vcd, and wavs I can`t see at all. I have the latest firmware version ends 1116 I beleive.
Am I missing something?
Cheers

No, The Dansai with only read Mpeg video and Mp3 music files.
