MKV files choppy

[Jflachs]

Hey guys, I'm wondering why I can't get 1080p mkv files to play on my computer without choppiness. At first it was very bad but I've been able to minimize it by using the latest version of CoreAVC in conjunction with Media Player Classic. During busy scenes however, there is still noticeable choppiness.

I don't think this is a hardware problem, my computer's specs are as follows:

Windows XP
Asus P5B
Core 2 Quad 2.83GHz @ 3.4GHz (8.5x400MHz)
4GB DDR2 800
Geforce 8800GT 512MB (Forceware 182.08)
WD Velociraptor

This PC should be able to playback 1080p video easily, so why the choppiness in busy scenes? I've tried closing all my background tasks, disabling my second monitor, and using ffdshow instead of CoreAVC. My CPU usage never even goes above 5%.

I've never seen a movie from a Blu ray disc but I assume it doesn't playback choppy on a PS3 or a regular Blu ray player. Does this have something to do with the mkv container? I've played 1080p avi files before and don't seem to remember them being choppy. Any ideas?

Have you tried using VLC?

Yup, you could try VLC player.

vlc plays them extremely poorly, that's why i'm using MPC in the first place. VLC is usually my player of choice but it plays them worse than any other player i've tried

jetaudio plays mkv with no problem

I've heard of people playing mkv files with DirectShow players and Windows Media Player perfectly with the 'Matroska Pack'. You can check it out and see if it works.

Since you have a 8800GT 512 MB, it probably has the G92 core which means that purevideo can assist in CPU offloading for playback. Some players support purevideo as part of the playback, which can definitely help smooth things out.

My personal combination for flawless playback of 1080p files is as follows:
* Purevideo CODEC (which allows you to tap into that G92 core)
* Zoom media player (supports purevideo and numerous other CODEC's)
* FFDshow
* Haali Media Splitter

When I start an MKV file, all 4 of those are in use for flawless playback and crisp sharp pictures.
