Footage plays out of sync in Final Cut Pro

Hey all!

I was given AVI files that I coverted to MOV files. Once I placed them in my timeline I saw that they were all out of sync. I checked the format and it says that the audio format is 32-bit Floating Point. I am guessing this is the problem as the sequence settings only allow me to pic 16 bit or 24 bit. These files are also out of sync when I play them through quicktime player and MPEG streamclip....

The guy I got this footage from (A PC user) had no problems with the footage being out of sync...

Any ideas on how I could fix this????
