Hi, i am having nothing but sleepless nights sitting up till the wee small hours trying to figure out how to get a codec for an 'ms' file? i downloaded the f1 grand prix and I get pic but no sound... its in AVI format and when i open in quick time pro and request info it says the format is 'ms'. some where i read that you had to get a codec for this and place it in your /library/quicktime/ but that file doesnt exist on my HD either... pulling my hair out, please help!!
