You could export the Replay save file so you could import the files on another PS3 to see the replay in game on your friends GT6 for example...
If you meant viewing the replay such as MP4, avi...etc on PC then i afraid you had to get some Game Recorder Devices to record those replays...
OK! Thanks for the help. I was wondering how so many people could do this, but I couldn't.
The options you have for Game Capture devices are Hauppauge, Roxio and Elgato products.
