It works very well. But. I run Linux, and an add-on Linux dependency file to allow downloads from YouTube, or some other sites file IS installed, in fact twice, and VDH consistently informs me that that file is not installed.

Pr0nHub (hey, I'm 70) frequently shows files in bytes, and cannot connect to the actual large file, as it reliably used to. It isn't with every video, but it's with a lot.

A hint: If you're downloading several files, and one is downloading very slowly, choose Abort for that file. Other files will continue downloading, and the slow one will eventually finish.

Lately, it shows 480p instead of file size, and I have to refresh the page over and over until the filesize appears in Mb.
