--- Comment #22 from Alex cerebro.alexiel@gmail.com 2012-07-14 07:35:02 CDT --- Actually, I always used the ISO because of the slowness of my CPU + the fact I had to use the software rasterizer (poor VIA graphic card and bad driver).
The issue was also present with the ISO and since an ISO is a byte-by-byte copy of the real disc, I thought it was the same.
Sorry for the confusion.
