It works like Windows Media Player, with a side menu where you can find lots of channels. Choose the one you want to watch and enjoy.
The interface of the program is as simple as intuitive. Choose the genre, and then, the channel, that's all.
Sports, children, nature, news,... you have a good range of options to enjoy online TV.
No settings, no configurations problems, just TV. gE3k TV can be a good choice. Specially if we think that it's still being developed and that it allows us to watch some channels other programs don't.
