Vlc on android box

Hi
I have a m3u file which I watch on vlc on my laptop, it is quite easy to change channels and search for channels. I was also trying to sometimes watch the same m3u on perfect player on an android box but it was poor. Therefore I downloaded the vlc apk to the box and added the m3u to it and it opens on BBc 1 , however I cannot seem to switch channels, was wondering if anyone knew how to move about on vlc on an android box?

Thanks in advance.

On the android box try using ihe iptv app avaiable from the play store.
