Question regarding video players

OK. I am tired of trying to figure it out what the hell is wrong, so I need help.

I just can’t see movies in my computer, because the rendering is slow and I see pixels, when I am not supposed too.
For example…

Tekkaman Blade anime, I downloaded and see in Living room Dvd Player. But in my computer, the image quality is incredibly different and the subs are annoyingly Pixelized. But in my dvd player I see no pixels in the subs.

another thing is the I see the rendering being slow, specially when there are very fast scenes in the movie, and it seems the rendering a can’t process that information.

It can’t be something about my computer processor. The computer is brand new, and with 6GB of memory processor. The only thing I can see is the software or codecs.

I use Media Player Classic with K-Lite 9.9.0, and my OS is Windows XP.
I tried with the Windows Media Player default of the OS and it does the same.
Anyone can help me please? :/

I am getting desperate, as I can’t think of anything else that might be wrong with it.
I just formatted the computer. And done nothing different….

Interesting ! Let us try figuring some issues first.
So 1- Are these problems occur only with this anime in particular or does it happen to all videos ?
2- These things only happen when you are in the full- screen mode. You should try seeing the anime in minimized screen and see whether if the problem persist ?
3- Are these mp4 video files ? Are there any specific video files that are causing this problem ? If not please name the formats that are causing this issue.

As a primitive solution I suggest using totally different player for the sake of trying. Kmplayer for example. And another thing that might work out try to fully convert the videos using free softwares for conversion such as Allok 3GP PSP MP4 iPod Video Converter or any other one could work too.

Thanks, awaiting your feedback !

it happens with all videos and formats. And the fullscreen mode , NO it would not do that. I know because I have been testing it with files I already saw in here.
I have already tried other players and it does the same

ok. after one months around this thing….

The problem was of Graphics.
My computer is ACER ASPIRE XC600, it came with win8….. but fuckt that I formatted the pc for winxp. The drivers for it were not working right.
So, after 1 month looking for compatible drivers…. and lossing hope, getting desperate, and posting here for it….
it was for nothing, because 5 minutes ago…. I got what I need it.
Seems like every time I go desperate in something and post help here, no one ever helps, but I got what I need AFTER I post here.

FFSHRINE IS REALLY A LUCKY PLACE.
Will I get lucky and get teh girl of my dreams if I post here for help? XD
