I own a Sony HD camcorder hard drive, which offers more recording on Memory Stick PRO Duo. I made the purchase of this card simply to share photos and videos, as HD movies (AVCHD) are not easy to record, burn or read on other machines (PC or Mac) (files too large, sometimes incompatible with some editing software, storage and burning recommended only on Blu-ray ...). I cut my films in less than 4 GB file, I transfer them on the map and I can read without problem on other machines (or almost). Good map. Very "PRO".
