I got part way through it before it failed also. I tried a different program & was able to get it.I actually don't use RealPlayer very much anymore.
Getting Youtube "unable to download" today 3/27/2020
Some videos will download and one won't. I tried with Firefox, Chrome, Edge. I followed the instructions on the post "getting Youtube "Unable to download" as of 01-24-2020" but it did not correct the problem. I am on Win10, all browsers are up t date. My version of videodl.exe is 2020.03.01.
This is the link for the video that will not download: https://www.youtube.com/watch?v=5boo08FaGt4
Jon Rogers what other program? I would like to try another also.
