I got some iso's, and they also come with a SFV file and a MSINFO file in each folder as well as the RARS. Do I copy these to the DVDR with the ISO, or are they just rubbish. If I did copy them as well, would it make any difference to the running of the game?

the iso is what you want to write to the dvdr. use primo prassi and browse to the iso and burn it.

the rar is probably what made up the iso. if you extract the rars it makes the iso.

The SFV is just to check the archive is intact, the NFO is just information about the game. No you dont burn either of these to the disk, I cant see how you could anyways using the ISO burning method.
