ok, I got a movie file off the web, it was the .rar with all the broken up peices .r00-.r84. I used winzip and winrar and both convert it to a .iso. poweriso opens it up and extracts it back to .rar. also I tried using poweriso to burn and it never got past the initial check, so I mounted it to the virtual drive, copied it to the dvd drive using windows explorer and burnt it and the PS3 showed the disc but said data disc, and then when you try and access it it says no titles. and it filled the entire disc. so I tried with expressburn and it acted like it did it fine, but the disc looked only 1/3rd full and still no luck in the dvd player. I dont know what file I need to end up with to make a playable DVD. is it just I dont have the right software? I have winrar, winzip, xilosoft dvd creator, poweriso, isoburn, expressburn, and converters to get almost any video format to another type. obviously this iso was made from a dvd, then converted to a .rar for easy transfer, then when I go back to iso, then burn it, shouldnt the iso burning program extract it to the original dvd status as it burns?
