I am trying to watch a 1280x720 h264 .mkv file on my computer.

My computer is an Intel 2.4 GHz dual core (E4600) with 2 gigs RAM and an nVidia 8800GT video card, running Windows XP. It should be able to play anything I throw at it, but I get frequent stutters using vlc 0.8.6f and the latest Community Codec Pack. I have checked to see if vobsub is installed and it is not.

What can I do?

I still think it’s the CPU choking. H.264 is a very processor-intensive codec, so even with the latest processor, you never know. Here’s how to check. When you play the video, right click on your taskbar and choose task manager and look at the performance tab. Is CPU usage at 100%? Then look at the processes tab, and click at the CPU tab once or twice to sort processes by CPU usage. Is the VLC taking close to 100% of CPU usage? Or is there another background process competing with it and keeping it from making use of the processor? If the latter, you could kill the process if it is a non-essential program, or try increasing the priority of VLC (right click, and pick a higher priority).
