Why is DivX player more crisp?

I've been watching videos (.avi, .mkv files) using either Windows Media Player 11 or VLC Media Player 0.8.6. Recently I downloaded DivX player and noticed that videos watched in DivX player appeared to be much more crisp & sharp hence making them look clearer and better. Why is this? This difference exist between Windows Media Player/VLC Media Player and Media Player Classic as well but not between VLC Media Player and Windows Media Player-they look the same, to the naked eye at least. The difference is also more noticeable in HD movies (.mkv) than regular videos (.avi). I've also got the K-Lite Codec Pack installed.
However, videos watched in Windows Media Player and VLC Media Player appear to be more smooth in playback as compared to Media Player Classic and DivX player where the video can look/feel slightly choppy, not extremely noticeable but it gets slightly disturbing to the eye, especially when there is a lot of movement in the video.
I've got a HP Pavilion dv6000 notebook running Windows Vista Home Premium. It's got an AMD Athlon 64 X2 Dual Core 1.7GHz Processor TK-53 with 2GB DDR2 667MHz RAM. The graphics processor is nVIDIA GeForce Go 6150 running on ForceWare Version 98.15 (from the HP website).
Obviously I want to be able to get the smooth playback that Windows Media Player & VLC Media Player offer with the crisp and better looking video quality Media Player Classic and DivX Player offer. Is there a way to fix this? Or, can anyone tell me why it is like this & how or what I can do to get the two as close as possible in any or all of the players?

 

Hmmm I've not come across such a noticeable difference but I like to use Media Player Classic for playing any kind of video rather than Windows Media Player or any other equivalent ones.... Media Player Classic has more control over the video and audio outputs than any other player I've come across.... Also MPC is less resource hogging compared to WMP....

 

Divx has a post processing feature to make each frame crisper,richer & sharper..

Go to preferences while using other players & see if they have it too...but DivX post processing is better than WMP

 

I also like the WMPC. Dumb question: Why did Micro$oft screw up one of teh few good things Windows has? The media player was fine for all the reasons you state above and then. . .they tacked on all that gook.

 

I love the new WMP 11 - mainly because of the library which, with its thumbnail previews, is just fantastic to keep track of and search through the hundreds of videos I've got sitting around on my external harddrives.
Significantly better than any other media player I've tried.

And fortunately they've also added the one thing (and a rather simple one at that) I was sorely missing in WMP 10 - time line and playback controls in full screen mode.

Don't know about the "quality" differences, but as nocturnal310 says, a post processing filter sounds about right. I can't really see any other explanation for it, even with different codecs (I believe VLC uses its own codecs for instance?).

 

But why does Media Player Classic look nearly as good as DivX Player (marginally different) but get slightly choppy with this crisper image? Does that have a post processing feature too?

this is imho the best player for videos. it's compatible w/ just about everything.

 

Oh really? Well maybe i should re-install Divx with the play to check, my video loose quality when i go fullscreen but if i can get them crisper that would be awesome.

 

MPC has lot of plugins and filters that can be installed too.... I think you can find them easily on the net and try to get hold of a similar post-processing filter and see if it improves quality....

 

Starting from Divx 6 i think there is an option on the Divx decoder for Full post processing and sharpening. This is not default option on the codec config but maybe the divx player got this option turned on by default.

 

You can use the DivX decoder in Media Player Classic as well for decoding....
