There are someway by which you can modify the setting of the VLC media player which finally can help you to watch IPTV with less buffering by increasing the cache size. In the following, some of these tips are mentioned.
How to optimize VLC
1: Open VLC media player, select "Tools", and click on "Preference".
2: Next, click “All” under the “Show Settings” option at the bottom of the window. Click “Input / Codecs” in the left sidebar.
3: If the file that is buffering is playing from a local hard drive, look for the “File Caching (ms)” option under “Advanced” on the right side. The caching value here is estimated in milliseconds, so setting the value to 1000 will buffer for 1 second. The issue with setting this option too large is that if you want to manually skip to a new point in the file, there will be a larger lag while the content is buffered again.
If the file you are trying to play is located on a network share, you can change the caching value for “Network Caching (ms)”.

Type the URL you want to play, then click on "Show More Options" checkbox.
Now, based on your Internet speed you can increase the cache size.
