I just purcased a Canon Vixia HF200 and want to use card reader to download video to my computer. I have searched using google and forums wirh no success. I find many cases where it says how easy it is to use a card reader but nowhere can I find out how.When I open the sdhc using the reader what files do I transfer to my computer to edit, make a movie and burn a dvd. I know I download mts files but what do I do with all the other files on the sdhc? Delete them, leave them or what? Thanking for any assistance jim_joh
