When you dl an ISO and burn it. Is it possible to lose data and textuers......

The only way that you could loose textures and data from a game is if when it was originally ripped from the GDROM some of the data had to be removed in order for it to fid on a CDROM. I you downloaded an ISO. I don't believe it will even burn if the ISO is not complete. But who knows.
