Where Can I find a good easy-to-use PS2 movie player?

I have a PS2 movie player,I found it on mega games.com but I can't use it.

I want to play PS2 movie files(.pss) with my PC. I want a simple easy to use player. I have downloaded the "ps2peng" from your that site but it doesn't work. I'm not an expert in computers and windows,I unziped the file. Now please tell me what exactley I have to do(Considering I'm a kluts). I coppy and paste what it said in the "read me" file about plug-ins. I press start,run and type in the command but an error message pops up and says:"Loadlibrary ("C:\program") failed. GetlastError returns 0*00000485".

Please help me if you know how can I use this player or if you know another one!

Thanks to all!
