Most videos show up, but require a 'companion app' so you can't download them without installing their software that takes up more space and does who knows what for who knows what reason

Дополнение работает.
Но! При сохранении видео, когда выбрано "сохранить" без конвертации, всё равно выполняет конвертацию только для того, чтобы вставить QR-код с уведомлением о том, что для конвертации нужна лицензия. А я, напомню, конвертацию не просил.
В результате вместо того, чтобы просто сохранить полученное видео за пару минут, дополнение 2 часа делает переконвертацию (с заметной потерей качества, кстати) только ради наложенной картинки с QR-кодом.
Это идиотизм и непорядочность.

So you're asking me to donate money to you every (n) files that I download with your addon while at the same time strapping a gigantic, 100% opaque watermark in like a quarter of the videos I download that you're basically asking me to pay a $20 ransom to remove? What a great idea. I feel SO inclined to give you any money.

It is paid. Not free !!!

Stop opening new tabs and distracting me from my work....this addon doesn't even work half of the time. Instant disable.

Useless without installing its "additional app". What's the point of an addon that doesn't run by itself?

everything was fine until about a few months ago. i download mostly from youtube, when about a quarter of downloads didn't work, and then some wouldn't delete, causing havoc on my computer, and many restarts. hope this new ext solves the problem.

Устарело - последнее обновление 9 месяцев назад. Часовое видео с Youtube в 480р скачивается и конвертируется почти 2 часа, сохраняется без названия, еще и с водяным знаком и просит купить лицензию.

갑자기 QR Code.. 안 써.

Does what it should, but ADP-based video sites (YouTube etc.) require a conversion with this app. When doing so, it gets stuck on a lengthy "aggregating" process, wherein it is applying a watermark to the entire video. This process is throttled and takes ages (over an hour for a <5 minute download.)

Paying a whopping $30 USD for a license skips this step completely. Which is to say it's completely unnecessary, and exists just to twist your arm for cash. No thanks.

I've used this add-on for a long time, but more recently it seems any video (and I mean any video) adds a watermark upon download, and apparently the only way to avoid this is to register and pay them. Maybe I'm using it incorrectly, but I'm disabling it now.

Way too much of this add-on requires an external application or redirect. That's ridiculous that even the "quick download" (the most basic function this add-on exists for!) requires it. I see this hasn't improved at all since the last time I'd had it installed years ago.

It seems to be quite nice at first glimpse, but, the "aggregation" puts a big (really big) QR-code to the upper left corner of the downloaded videos, in order to force you register (==buy). And does it causing a huge load to the CPU/RAM/GPU for minutes or quarters of hours(!). And several cases this "aggregation" is the only option - despite, what is written in the description.

Sorry to say but the video downloader is great for a lot of different porn sites that it works well for flash downloading of such sites. The reason I say it's sad because I wanted to use it for other sites besides porn but oh well. Anyway when I try to use it for other sites as other users have mentioned there is a watermark and I have also seen the whole movie image looking like your looking through a screen door or window. Also after waiting for a very very very long time like over an hour of downloading a movie there will be two files in the dwhelper folder in users of drive c: that will be one for video and the other for audio. I have waited also for almost another hour for the whole thing to complete or merge the two files. Yay another watermarked video... Oh Goodie (not really). Well I guess I will continue to use this for only porn then as that is all it's good for.
