Play all multimedia files and find subtitles automatically.
BS.Player is a free video and media player that's been around in several versions for some time. It's a capable tool with lots of options and some useful specializations, such as automatically scanning your system for missing codecs and downloading and installing them. It's got some clunkiness, though, and it displays a nag message overlay when you play videos. It's only on the screen for a few seconds (though it seems longer) but all it does is tell you that BS.Player is free for noncommercial use.
