SO I downloaded the FF13 E3 06 trailer in HD from gametrailers

it's WMV. 720p or something like that

how can convert this so my PS3 will recognize the file

I TRIED PS3 VIDEO 9 but it doesn't work and keeps crashing before it starts

please help cus I need to show the trailer of in Hd to my friends coming round tomorrow

So what do I use APART from Ps3 video 9 n can I use the PSP to transfer the file?

use your pc.

ok for real. WMV, in case you didnt' know, Windows Media Video and is by default playable through Windows Media player, which does not run on Linux or non-Windows machines.

So, either find a converter or a media player for your ps3 that has the appropriate media files for wmv.

Or just read my first post.

SuperC will convert it... It's kind of funny to install cause the person(s) who made it didn't want people distributing it besides through their site. It's free though.

You have to scroll to the bottom, click download, then scroll to the bottom of a screen that looks exactly the same and choose the download. (Pain in the ass if you ask me.) But it will convert pretty much anything to a PS3 acceptable format (Select PS3 from the list)

or if you have the PS3 and PC connected to the same LAN, you can use TVersity to transcode it to the PS3, but I wouldn't do that to show it off (depending on your LAN speed and computer, it can stutter)
