Burning Playstation ISO

[forty]

I have an ISO file which I want to burn to CD to play the game in a playstation.

I have tried.....

1) Extracting all the files using WinISO & then burning with Nero.
2) Burning just the ISO file with Nero.
3) Burning an 'image' of the ISO file with Nero

and probably another 1 or 2 different combinations, but have had no luck.

Where am I going wrong ?

Any help appreciated, thanks.
