Slow playing large mkv files in ubuntu

Asked by Wyn

I'm having Problem running large mkv files (6Gb).

The video play slower and the graphics goes wonky or distorted/pixelated.

> I'm using Natty 11.04
> My video card is NVidea 6150 GE. 256mb
> AMD Athlon 3800+ Dual processor
> 4GB memory
> I have no problem running Compiz and Docky in my video card which means my video card is recognize by the system
> I've tried using totem, vlc & mplayer but the problem is still the same
> I have no problem running other video formats (avi, mp4, dat, other vlc files that are less than 4Gb, etc...)

The file is not corrupted, my friend tried playing it in his brand new Samsung laptop running Windows 7 and works fine. Unfortunately, I didn't had the chance to take the specs of his laptop.

I'm very confident that Ubuntu are more processor efficient than Windows.

Do I need a large video memory or more processor power?

Thank you in advance for all your reply...

I already solve the problem.

I converted the mkv file to playstation file (mp4) through Arista converter. It took me a while to convert but it's worth it.

I sacrifice the video quality but at least I can watch it in my PC or PS3.

Thank you all for your reply
