Ok, I have built on Emgmex's idea, and have gotten the new youtube-dl script to work somewhat. I have had to hack it so that its stdout looks similar to youtube-dl-x. I'm not quite there yet, but you can at least hit the download button, and watch the percent climb until it hits 100%. Once it does, you can hit the play button.
lines that I changed in youtube-dl are lines 360,361, and 382.

My guess is if we can get the stdout to look exactly like the youtube-dl-x, we should be good to go.

Edit: go here to get the deb, which installs Emgmex's modified script.
