Hello, you can view only the video and also download it to your mobile device.

Hi, maybe this feature will be in the future.

What's your app version (can be checked by pressing "Alt" < "Help")?

For the better understanding it'll be great to see a screenshot with the error. 

Hello, the program only downloads from Youtube, it does not download from other sites.

Hello, where exactly can not you download the video?
Describe more in detail, send screenshots.

Hi, can not you download a video from Youtube?

Or you can not download videos on your mobile device from your computer?

Hi, do not quite understand your question, please describe in more detail.

Hello, you can go two ways in order to delete videos from the app.
The first one is the simplest one — just click on a three dots icon in the right corner on the video preview and choose Delete file.
The second one — go to your Downloads folder and find there Televzr Downloads, all your downloaded videos are there.

If you have the opportunity, take a video of what exactly is going on and send it to us. Thank you.
