John bought a 60GB hard drive to rip VHS tapes and digitize them, but they won't play on most of the computers he's tried. Leo says that file size could be an issue. There's a 2GB and 4GB barrier and he'll need the most recent version of Windows 7. The other problem could be the codec John used to encode the videos. Leo recommend VLC VideoLan Client. Leo also suggests reformatting the drive to NTFS so he can play the larger file sizes.
