Hi, i cant download any of those nice videos!! When I click Download it prompts me to log in, so I do. Once I am logged on it takes me to a page that says I have to subscribed threads, not the download..
You need to go back to the videos after logging in. AT the top, click Gran Turismo 4 and then go to videos. Or, click Welcome and click on the link to the video you wanted.
Most of the time the problems are the cookies on your computer. Delete the 'gt-planet-cookie' and try log in again. Then go to your game and you should be able to download those video's. In some cases (like me) you also have to reboot your computer.
