even with my high speed cable modem viewing was stuttered at 1080p..........but the original was just as enjoyable for me.
Try the 720p HD setting, and give it a minute or so to buffer first.
This is the optimal setting for people that have high speed internet and a larger display monitor.
720p HD picture size, sharpness, and overall quality is dramatically better
than any of the lower settings.
btw, you're able to download and save to your PC YouTube videos
here. You are also given a video format and file quality/size option. It's free. Enjoy.
