If ALShow can't play that video clip, you're really sunk--this
media player claims to handle every codec out there, and that
appears to be true. In addition to the dozens of codecs included
with the file (everything from AVI and MOV to Ogg Vorbis and
beyond), the program automatically seeks out missing codecs and
downloads them on the fly if needed.
Not only that, but ALShow does a great job with playback. Clips
are smooth and audio is clear, even with files that don't play
smoothly in other media players. You can even output video files to
a TV screen. Other features include Favorites and Recently Played
lists, plus audio and video capture modes.
