VLC may have been one of the first universal type multi-platform players that could handle everything without the need for a system-polluting codec pack, but it sure never felt like a true Windows program.
Clunky UI, convoluted settings, and general lack of niceties found in other modern players really hold it back (even though it "just works" for most folks).
Not to mention taking forever between versions. Will 4.0 ever be released?? And finally have seek bar preview, for example? Maybe someday VLC will be a worthy alternative again.
