avchd player

[Ledzella]

Is there a player ( software to put on computer) that will play avi format without needing to decode it to something else first? The reason I ask is because I use a panasonic HDC-SD9P/PC (AVCHD ) camera with SDHC Sandisk memory cards and would like to erase the cards once I transfer files to my computer, however if I can only play the files by converting them to some other format, how will I know if they are exactly the same as what the video camera had in terms of quality of picture and original sound? Thanks, any suggestions?

If the new BluRay Panasonic home theater players ( can not afford to buy it just yet according to wife economics 101) have a slot for the same SDHC memory cards and can play them back surely a computer should be able to do the same with the same files transferred on to a computer as long as they are the same, right?
