yes and no.
after you rename the rar to iso, you would be able to view the contents with a iso viewer but as for making a cd with autorun and so on if you wish, it is not enough. you will need to create a cd out of the extracted contents from the rar file. you could use nero or sonic or most of the cd burning software out there to create a data cd, after that when you want to rip the disc, you will get an iso file.
