First, the basics: VLC 1.1.4 on Windows 7 Pro 64-bit. I have already tried resetting VLC settings and cache, but the problem still exists. This happens with or without GPU acceleration.
I've watched a couple DVDs recently, and I've experienced this problem with both of them (these are retail DVDs, not burned DVDs). I'll be watching the DVD fullscreen, and then out of nowhere, VLC will exit fullscreen and immediately go right back into fullscreen. The audio is completely uninterrupted, but the video is obviously interrupted for 1-2 seconds. This happens about once every 15 minutes or so. Right after it happens, it typically happens again within about 30 seconds. Then, it won't happen again for another 15 minutes. It seems to happen most often right around chapter changes, but it also happens sometimes right in the middle of a scene, so I can't really say that's it. I've looked in the settings, but I have on idea what might be causing this. There's no issue when watching video files off of my hard drive; this only happens when I'm watching a DVD.
What's going on here? This is incredibly frustrating.
