I am sure quite many of you experience movie viewing problems, mostly those of you who enjoy viewing movies more than playing games(like me). I really enjoy watching movies(good ones), they make me feel good and when my morale is down a comedy always raises it.
I remember back in the days on my old pc (350mhz/56 RAM) i couldn’t watch some movies because either the sound/picture we’re moving with delay or the movie was going almost frame-by frame and was unwatchable.
But since than i gained experience and figured out a great combination of applications that will help you view any movie without any problems and will help you experience the highest quality video and sound.
Make sure you follow the order of the installations, otherwise you may encounter problems when viewing movies.
1) Ace mega codecs pack
This is the lastest and greatest release of famous ACE Mega CoDecS Pack.
In this codec pack you will find plenty of usefull CoDecS (CoderS/DeCoderS), Media Player FilterS, Media Players and other UtilitieS. Also I added Authoring ToolS for video watchning, audio and video processing. In Add-On Pack you can found Authoring ToolS for content creation.

Make sure you select Professional edition from drop-down box, as this will install all the codecs along with media player classic and BS player. When It will ask you which programs to bind to be opened with media player classic select all the video files.

2) FFD Show
ffdshow is DirectShow and VFW codec for decoding/encoding many video and audio formats, including DivX and XviD movies using libavcodec, xvid and other opensourced libraries with a rich set of postprocessing filters.

When installing make sure you select all the aplication plugins as some AVI files will require it to run smoothly.

3) Matroska Splitter
Haali Matroska Splitter is a new DirectShow splitter, based on Haali’s C library (the same library used in Betaplayer, the first player for PocketPC with Matroska support) for .mkv (Matroska), .mp4, .ogg/.ogm and .avi handling.

Exactly as FFD Show make sure you check the “Enable AVI support Box”, if you have MP4 movies they won’t run smoothly without this application.

4) VLC Media player
VLC media player is a highly portable multimedia player for various audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, …) as well as DVDs, VCDs, and various streaming protocols.

At Instalation type select FULL install then uncheck the file type associations box, remember you want to open your video files with MEDIA player classic and audio files with winamp/or music playing program.
To be Brief: VLC PLAYS ALL! IF media player or bs player won’t be able to run a video file smoothly, run the file with VLC and 99% that it will work.
