PS3 games are on Blu-Ray Discs not on DVDs although they are the same size.
No there are codes in the game disc that the PC can not access that do not copy
Currently, no. You should get a PS3 to do that.
The DvD ripper will copy the information from the disc, it will not remove the information off of it.
bluray
You can play Starcraft without the disc by downloading it or burning the copy into your computer.
iso modding is when you copy a game to another empty disc and inject mods to the disk
blank dvd-r disk
If you want to copy them as in insert disk, then save it... theoretically you could save it as a disk image, then try to run that if it can read the disk, but this isn't necessary.
depends on what kind of disk you have. music disks you can copy but it is not illegal unless you sell it. dvds are illegal to copy in the first place.
there should be copy disk option
The PS3 for example does not keep the whole game disc downloaded in it's harddrive and if a disc is actually identical how would the device know that it was a different disc and a copy could not be identical because certain areas or the disc are not available except for professional or commercial equipment
there should be copy disk option
