i just burnt snow surfers for DC and it loads up fine.. i pick my character then my track and as the track starts to load i get this mad lous grinding noise.. it sounds like the dc is going to blow up! does anyone know what this is?

It's struggling to read the data from the CD.

Recopy adding dummy tracks or burn slower to a good quality CD. This should help. I had the same problem and the slower burn helped considerably
