Have never had this problem on windows xp, but have noticed on vista 64 with my new build. Some game will install a certain amount and then give me a Error 1305, and say that there has been an error reading a certain file from the dvd, and ask me to verify that the file exists and that i can access it. The files are all present on the dvd, I can click retry and then the installation goes abit further then gives me the error again. The only way i can get around this is if a copy all files to my harddisk and then run the setup file. I have a pioneer dvr 212 optical drive. Any ideas
