For everyone, who doesn't know how to handle psd files:
I resized EyeShotFirst's image to the dimensions that are given in his template file and edited it slightly in photoshop. It is not possible to maintain the original aspect ratio though, since the dimensions wouldn't be correct then. All that is needed now, is printing it out in it's original size (from image dpi). I hope it's correct this way, I had no chance to test it yet.
I made two versions (both high quality jpgs): One with the AVCHD logo and one with the Blu-ray logo.

I mainly made those for myself, but thought, what's the harm in sharing them here. ;) All credit goes to EyeShotFirst. Can't thank you enough!
