The VideoLAN Forums

Recently, on full-screen, any video file I play has a choppy playback; it sort of pauses, the video, while the audio continues to play for a second or two, and then it catches up. It is also have those blocks of video for a few seconds (hard to describe, but the large blocks of bad video data?); it never did this before. I recently installed Windows Media player and have to reset the computer (this computer I hardly reset) I do not know if WMP is the cause of this or not; thank you.

I also upgraded to 213 and the same thing.

I just had a similar problem using 2.1.3 on Windows 7. The video was occasionally choppy or pixelated and then would freeze in fullscreen if I moved the mouse or anything but the audio would continue and sometimes loop.
I don't really know anything about vlc but managed to figure out a fix using a combination of post answers and the troubleshooting section. Hopefully it will work for you. Here's what I did:
Go to tools > preferences
In the left panel click 'video' and make sure that 'Accelerated video output (overlay)' is ticked.
Where it says 'output' I selected' Directx (directdraw)' since i'm using windows 7 and dont use aero but the troubleshooter has this to say about the choices:
"There are multiple output modules you can use. For Windows XP and younger you can try DirectX 3D, DirectX, OpenGL and Windows GDI video output modules. With Windows Vista and with Windows 7, both DirectX and Windows GDI output modules will disable Aero, so if you want to use Aero, please use DirectX 3D (should be default)."
Next click on 'input/codecs' in left panel. Under 'codecs' I had 3 options: disabled, automatic or 'Directx video acceleration' which is the one I chose as it was disabled by default. I'm not sure if that's what you'll have but if not that one then whichever comes up instead of disabled or automatic might be good?
Remember to press Save to save VLC settings and restart VLC after that to make sure changes are enabled.
I really hope this helps since it took hours of hunting the forums and troubleshooting section before I found something that worked!
