GOM Player has great loudness and normalize function, very useful in horror movies. Pot Player is great and has lot of options. Splash have great high frame rate mechanism. I don't think that using FFDShow is needed these days just for viewing movies. Of course I have MPC-HC too and lot of other players (except VLC), so I understand that FFDShow or similar tools may be useful, but still - it's great when program has everything built-in like Pot.
