Thanks for the script, baderj

Updated the script to resolve errors with quality resolution. "live" seems to be the only 'quality' returned anymore. Also: added support for download directory creation, cleaned up a few sections, improved output of current download status, added content-type check to avoid downloading non-flash files.

Nice script,
I've also written a small script based on yours. I have connection issues with my Provider somtimes, so my script is able to resume downloads. I convert the Videos to mp4 after downloading. (requires ffmpeg)

As the first command line argument. But the script probably wont work anymore.

Use youtube-dl instead, works perfectly
