Hi there,

your AVCHD files will play back on a PS3 without conversion. The PS3 can play raw AVCHD files with no problem.

The easiest way to do this is to get a USB stick, create a folder called "video" and copy your MTS/m2ts files into this folder.

Plug the USB stick into the USB port on the front of your PS3 and it will detect the drive and let you navigate to it under the Movies area.

Good luck! Let us know if this works for you.
