Vista - AVCHD Capable Video Players?

So I have a video camera that shoots 1080p and saves the clips as *.mts files. My quad core at home handles playback of the files in VLC and WMP, however my laptop tends to choke up on them when using VLC or WMP. I have managed to get them to play flawlessly using the Oxygen Lite player, however I was wondering if anyone else has additional suggestions, or has had better luck playing them in VLC? Oxygen manages to play them by turning off glass (which I tried to do with VLC, and they still suffered playback issues). I could easily convert the videos to a much friendlier format I know, however I'm keeping them in their raw format for archival purposes. Unless someone can suggest a lossless format, I'd rather keep them in their raw format until I get a chance to return home in a few months and edit them on my primary computer.
