Perhaps some of you might find this program useful:
"HamMultiPlayer is a software created to scan your directories (and/or drives) to find and display several files in real time. It can be used to find, move, delete or preview any video/audio file. This is a "portable" software, this means that everything is already included inside the ".exe" (no installation, no registry keys, ...). It uses mplayer and MediaInfo Library to decode and display files (so it can play everything mplayer can play). Program size is very small : 13 MBytes.
HamMultiPlayer scans recursively directories you selected and load any compatible file. You can then, sort generated list to find out duplicated or similar files."
