I can't play those media file such .avi & .rmvb. Got any recommendation for those media player like media player classic can solve it?

real player will do...

Bro, actually it's no so good to use RealPlayer as it's meant only for ".rmvb".

actually real player is more than that... go take a lok at the file type it supports, u'll be surprised...

RealPlayer is a bloated-self righteous- piece of crap. i'm sorry, but its a fact.

Install that Media Player Classic & it installed into my laptop but i can't open those multimedia file. 

just hang at there. 

pity you man.. which one did you download?

V6.4.9.0 

Did i deal with you before? Your nick looks familiar! 

you need codec/filter/put-media-jargon-here to go along with that player.

here's a suggestion :

VLC player - a little bit all-in-one with limited option to configure filter
ffdshow - complicated configurable codec with MPC integration

yeah, my beloved K800i came from you la

Do you means i need to uninstall my MPC & install those file that you provided?

P/S: No wonder. I checked my tradelist & found it.  I still got a lot of good model by now. 

Why nobody mentioned Kmultimedia player?  

I think a little explanition is needed.

99% of all "media players" (for Windows that is) relies on DirectShow which is a backend for codecs and decoders to work against. PowerDVD, WinDVD, Windows Media Players, Zoomplayer, BSPlayer, MPC etc all use DirectShow meaning that they're just frontends.

mplayer (not to confuse with MPC or WMP), VLC and KMPlayer all use builtin decoders which has both advantages and disadvantages. The advantage is that they're a all-in-one solution meaning that everything is included. Downside is that no other applications cant make use of its decoder(s) meaning that you still need to install a proper decoder for DirectShow if you want to convert a file to another format (unless you use VLC or mencoder to convert). Since they're builded with decoders you often have to wait quite a while before a new stable release is out meaning that files using new formats may work poorly or not at all.

I would also warn users for K-Lite Mega Codec pack, basicly its utter shit. It installs decoders incorrectly, several decoders which do exactly the same thing and on top of that often old versions. At least go for CCCP if you want a decent codec pack that's widely used.
I personally have my own developed "codec pack" that weights 5.39Mb using 7z, compare that to K-lite ;-)
