I have a Dell XPS L502X which went through a hard drive replacement a while back. I decided to re-install Dell Webcam Central and update it to version 1.40.37 which is the latest version it says is available. The software works fine for still capture and video capture up to 768x480. Anything above that (1280x720, 1024x768, 1280x1024, 1600x1200) results in the following error: "Failed to start video recording. There may be a problem with the video capture device or the audio recording device." And then it creates a small blank 127 KB video file.
I've checked the audio device and it's all in working order. I don't see how the webcam could be at fault because it can capture resolutions below 720p fine. I've even re-installed the webcam driver just in case.
