EX3 files not working in final cut

Daughter is putting a film together in college for a class. we rented an EX3 Sony HD cam to film. Finished filming and had little time to return camera so I took it with me, stopped at home and pulled the whole file folder off the card (about 13 gb's) Did not do anything but drag and past the folder to my windows machine. Files on the card were 4 folders: .fseventsd, .Spotlight-V100, .Trashes, BPAV and another looks like document named ._.Trashes

Inside the BPAV folder which is the only one I could open in windows were the folders: CLPR, TAKR, CUEUP.XML and MEDIAPRO.XML

She needed the files so I took just the CLPR folder which has all the clips she filmed and put them on a portable hard drive.

She is now at school and starting to edit and is crying because when she opens the files none of them look High Def as they did when looking at them on the camera. She was told to get a plug in or file from the sony site that would work in final cut. The files play in final cut but still do not look HD. Can anyone help her in what she could be doing wrong or offer any advice? Because she does not have all the files that where on the card be the issue? In one of the 150 folders inside the CLPR folder each one of the individual folders has an MP4 file, an SMI, a PPN a XML and a BIM file folder. Thanks.
