The basic reason is that the quality of videos on the Internet always depends on the number of users who are concurrently accessing them, and on the connection of the relevant server, as well as on the user, of course. If the 2018 World Cup final is on, problems are more likely to occur then than during a news broadcast at 3 o’clock in the morning. Another important factor, of course, is the speed of your Internet connection.

Issues may also arise on your computer. Some actions that you should definitely take:

Update your Windows to the latest version via the Windows update function.

Update your OnlineTV to the latest version.

Update your Flash Player version if you still have it installed. Even if the latest version of OnlineTV 15 no longer requires Flash Player, this program often ends up becoming so deeply embedded in the system that this can cause problems. Important: You must install Flash Player to run Internet Explorer and Edge. However, it’s best if you don’t install Flash Player at all…

Update the drivers for your graphics card and sound card.

If all these measures don’t help, deactivate your firewall and/or other security and tuning tools installed on your computer. If the connection is now more stable, check whether you can add OnlineTV to a whitelist for the security software identified as causing problems.

Is ActiveX activated in Internet Explorer? Check in the settings for Internet Explorer whether ActiveX/Scripting is activated. This option must only be activated if you have installed Adobe Flash. You will find these settings in Internet Explorer via the menu options “Tools” / “Internet options” / “Security”. At the same time, you can also check in Internet Explorer under “Tools” / “Manage add-ons” to see whether Flash has been activated.

If you are using a firewall, the following ports must be activated: Port 80 (outgoing TCP), Port 1935 (outgoing TCP and UDP) and Port 19350-65535 (incoming UDP).
