Further to that thought, you should not get VDH when you've never used it before &
immediately buy a license. Use VDH for a while & decide whether it works in your typical
use cases. If it doesn't, just uninstall it & move on, no harm done, no need to ask for
a refund. Once you decide it works for you, definitely buy a license. As I've said many
times, including upthread here, I believe it's the thing to do to buy a license & support
Michel in his work here. But don't get a license if you give it a test drive & it
doesn't work for you.
VDH for Chrome does not download from YouTube. If you're going to be doing a lot of
YouTube downloads, don't use Chrome & do get VDH for Firefox or Edge.
VDH makes no claim to work on every web site. The situation with multimedia hosting on
web sites is rather anarchic. There is no international standard governing the way web
sites host videos, which are the primary focus of VDH. In light of this, I have to say
it's pretty amazing that VDH does work on as many sites as it does. But it would not be
surprising if you come across a site where VDH doesn't know what to do. By all means,
report such cases here. Just understand that it might be quite a long while before your
case is investigated, if ever.
VDH does not download DRM content. To do so would be a violation of copyright laws. It
would be illegal. Don't expect VDH to work in such a situation. One of the most common
types of site where VDH does not work is pay sites, especially educational sites. The
fact that it is a pay site complicates the problem diagnosis process. It is against
company policy for the VDH folks to temporarily use your paid user ID & password. I, as
a non-employee of VDH, also will not do it. So if you're having a problem with a paid
web site, you most likely will have to post screenshots of what you're doing because
nobody here will be able to try things to see if they can duplicate your results.
VDH is available for Firefox, Chrome, & Edge. No other browsers are supported. I've
seen people in here asking about Waterfox, Chromium-based browsers, and other things I've
never heard of. VDH is not built & tested to work on those browsers. Safari, Opera,
forget them. It is possible that some fellow user has figured out a hack that makes VDH
work on an unsupported browser. In that case, that user is your technical product
support, Direct your support requests to that person. The VDH folks won't help you. By
all evidence, I believe Michel Gutierrez -- the guy who posts on here as MIG -- is VDH.
I believe he is the sole developer. It's quite possible he does other things in his
professional life that take priority over VDH. That's pure speculation on my part. I
don't know if that's a fact. We've got Jérôme (jcv...@gmail.com
) who appears to be an
assistant to Michel. His help here enables Michel to spend more of his time on VDH.
Jérôme comes on here & does his best to diagnose usage problems. He also handles all
licensing issues. But when it comes to diagnosing & correcting bugs, it's Michel by
himself. So don't expect the kind of support you might get from a multinational
corporation listed on stock markets in New York, Tokyo, London, Toronto, Paris, & Sydney.
All things considered, you'll probably get more than adequate support here despite that.
Also, understand that these guys are in France, so take into account the difference in
time zones when you ask for help.
VDH licenses are available for browsers on Windows & Mac. On Linux there is no license.
Michel has a soft spot in his heart for Linux & Linux users so he doesn't ask for a
license on that operating system. He develops VDH on Linux so maybe that has something
to do with it.
