After buying an unrecognized card (taken over by AMAZON very commercial way - thanks again) ... difficult to make another choice. I chose it after reading (only) 2 comments that clearly announced the operation under W7Pro + mention of compatibility on the site Connectland. A reception on the blister ... W7 is not referenced. Opening the blister ... on the manual, ditto ... Worry! I still started in the installation (I specify that I am not "pro", but it was done very easily). When you restart your computer ... new concern: I had to wait several minutes before you see open the "magic" ... pilot plant! Then the connection (very old) camcorder Sony DCR-TRV110E PAL (DV) ... And then rocked! EVERYTHING WORKS! Under the first 12 elements, the camcorder is recognized ... Hope these details will be useful for future purchasers can save a lot of valuable old films.
