ps1 help

[Rawps]

since i've lost my copy of metal gear solid 1 i've downloaded it (pal) by torrent. I have a chiped ps1 but have never burnt a game before and burnt it using this tutorial http://uk.youtube.com/watch?v=e53y_BZspmg
but when i start the game it black out after the anti-piracy warning, I can hear sound that the ps1 is trying to read the cd but nothing happens, can someone tell me whats wrong, im suspecting that the cd is low quality but I'm not sure.
