HELP? Need my fat ps3 to play mpeg-2 video files

Hello fellow PS3 users!
First off, I'm new to all this jailbroken, downgrading etc

I have plenty of mpeg-2 video files on my fat32 external hdd
But it quite simply cannot play or transfer over to ps3.
Haven't downgraded or jailbroken my fat ps3 yet.

Which file should I download for this type of files to work?
File: TS
Video codec: MPEG-2

Hopefully someone can help..
