Thank you. I have QuickTime 7 (not the free version) — and it says “QuickTime [7] features advanced video compression technology called H.264 to deliver brilliant, crisp HD video using less bandwidth and storage.” So are you sure I need to download something to see my files? Second, what is FCP? I am no expert but it would seem that everything I need to convert and play my files is self-contained in QuickTime 7 — but perhaps not. I have a Toshiba Satellite 1550 CDS laptop and I am using Windows XP.
