I've run into situations similar when the software I want to use for editing didn't support raw file type/codec.

I found a free file transcoder called MediaCoder and, so far, it has always recognized the raw file type/codec and easily transcoded it to a more program friendly type file. This utility program appears to be safe and I recall finding it recommended by Kim Kommando (Digital Goddess) at her website's download page.

Try doing a Google for mediacoder downloads or find the link at kim kommando.

I would suggest you transcode your camera files to mpeg2 which should be compatible with most all editing programs including the one you are trying to use. You do not need the expense or difficulty of use with pro software like Adobe Premiere to achieve a nice little program of your basketball exploits.
GoodLuck
