Why does the "downloadhelper coapp" start automatically (even re-starts when it's killed) and then ominously transmit tiny amounts of data every few seconds (to a Dutch IP, port 8088).
There's nothing to be downloaded, processed or otherwise and I didn't even touch the button or visit a relevant webpage to begin with.

5 stars for the add-on itself for being able to download videos from pages that don't provide a native way to download their videos (or streams).

It works well altogether, but the co-app's behaviour seems very suspicious at times.

Edit (2021/07/06): The VdhCoapp also not just starts seemingly randomly, but is also started whenever a "streamed" video is on the webpage, whether it is needed or makes sense at all or not.
The only situation the coapp should be started is when downloading (and converting) a video (or stream) *actually* needs it, but certainly not when the webpage is rendered.

There should be an option to force VDH to completely ignore the coapp even when it's installed and recognised.

Now a "license" is required or a big QR code is slapped on the video. This is a recent change. I normally don't mind paying for stuff, but at $30, that's really steep.

window bottom can't be seen unless full screen or switch to external monitor

fewer & fewer sites can be downloaded

no longer works with X/Twitter

Braucht ewig lange und dann permanent dieser Barcode in der Ecke...
Da gibt es Besseres.

es stürz immer ab und kann keine MP3 konvertieren

The App would be nice if they warned clearly that they add a HUGE QR code in every video you download, unless you pay.

Since 2 or 3 weekes it is not working properly on Raiplay website. I can only download the video but not the audio. Result: I have a mute video! It is impossible to contact the support team of Video DownloadHelper. / It was a great tool to dounload videos but now is full of bugs. / Depuis quelques semaines sur certains site (ex. Raiplay) télécharge seulement la vidéo mais pas l'audio. On se retrouve avec une vidéo muet. Dommage, il fonctionnait très bien avant. Il est presque impossible de contacter le soutien.

Unas veces descarga y otras no. No sé porqué

It's was the best Add on to download Video, but since 1 week now. The video only stay in "waiting spool list" and do not download anymore. What is happening???

No me funciona para mp4

Edit 2023: I hardly use it anymore. Whenever I would want to use it to download a YT video it striaght-up does not work. Modern internet sucks.

Kind of works, unless you have to deal with ADP or Full HD Videos. Will take forever to convert/merge/whatever the video after initial download. Unfortunately, not that useful anymore if you want Full HD videos.

Usually doesn't work..

does not function as claimed!!!

Ужасно. Совершенно неинтуитивный интерфейс. Поганит качество 4K видео при сохранении, запуская ненужную конвертацию, вставляя при этом QR-код в видео. Аналогично, при операции сведения локальных файлов аудио и видео. Ставит почти 100МБайтный модуль для работы - нахрена столько много? Впрочем, иногда видео в FullHD сохраняет нормально, только поэтому 2 балла.

So many download choices and some of them seem to be the same - I don't know which to pick, and most of the time what I do pick comes with video only - no sound. I could try again, and sometimes I do, but that doesn't mean I'm going to get a watchable video with the next try, and in the meantime I'm wasting data (and my connection has a data limit). On the rare occasions I've gotten something watchable it has a QR code in the corner, which is annoying. In trying to simplify things I've looked for a way to limit the formats I can use but the settings, of which there are a lot, make no sense to me. Basically - this is not very user-friendly and it works only rarely. The only reason I haven't removed it is because I can't find another option that works; if I do this one is going away.

It 'Requires' us to install a 3rd party app to actually save videos and who knows if it does so even then? If a company resorts to under handed methods to get business then it isn't worth mine.

When want to convert mp3, it wants you to download Companion Helper separately. Note it's AFTER you d/l CH and try to use it that it asks for money. Very sneaky, should be upfront and mention it before installing.
