Why do sound interruptions and/or dropped frames occur when I play high-definition
videos, such as those recorded with the AVCHD digital video camcorder?
Playing high-definition videos requires substantial hardware resources, such as CPU, GPU, or system memory performance
on your computer. During the video playback, some operations and/or functions may become unavailable, and sound
interruptions, dropped frames, and playback failure may occur depending on your hardware specifications.
