I may have a solution for your download problems. I have been using a program for video downloads that has a really good free version; I have recommended this to a few of the other members who had similar problems; this software is very, very simple to use and allows you to select the quality of the final download, download subtitles (if available), and download audio only; it also will work with a number of video sites other than YouTube:

I hope you find this helpful and I hope all is well with you...
