How do I post/view a replay?
To view a replay, download the replay, unzip it and put it on to your USB stick. Take your USB stick to your PS3, plug it in, select the USB stick in the Saved Data section on your PS3 XMB menu, find the replay you want to view on your USB, tap triangle and select Copy. Now go in to GT6 and navigate to the gallery. Scroll all the way to the right and click on the button "Open List" under Load File(s). Select the replay you have copied onto the PS3 and it will appear in the replay gallery.
