apehater: so basically same pic with different ui. is this wrong?
Well for example, in MPC-HC, under Options > Playback > Output, there are several various rendering choices ("Video Mixing Renderer 9") and whether they support hardware ("DXVA") and subtitles and so on. I doubt most people could notice a visual difference between them though.
My vote is for
MPC-HC too. Mostly I like the icons it uses for different file types and the minimal interface. (VLC gets the job done too).
As mentioned above,
Media Info to check file codecs.
If the OP is intent on using WMP, the
Shark007 codec pack is probably the best way to get everything to play.
For music,
Foobar2000, for the win! (FTW!) Endless ways to customize the layout to your liking. (Although not the most user-friendly to learn how, but once you set it up, so much fun to use. I've probably spent hours adding plug-ins and tweaking the layout and it just gets better every time. I'm kind of obsessed with it)
