Yeah right on. I still think you don't have to turn everything else off unless you are doing backups or so.
Also, it's the video that's the hog. If you turn the frame rate et. Al down and perhaps just show the spinning LP, you'll be pushing less data.
For example, take a look at some of the radio streams. They sometimes just have a static image or QR code. So their frame rate is like 1 because the image never changes and then they are just pushing audio.
But yeah, it's all experimentation.
