The problem with most of the youtube-dl scripts out there is that they do a full download of the file before returning any data to mytube, essentially eliminating half the functionality of the play button. You also don't get x% completed. You get spinning bar until it's finished. The last *fully working" script for mytube was a youtube-dl-x that downloaded youtube files "in parts". What's really needed is for someone to compare the latest youtube-dl with the previous version, extract the difference, and merge that with the latest youtube-dl-x script to form Voltron...er...a new youtube-dl-x script that interfaces with youtube correctly while maintaining all the old functionality.
