I see.
Here is how I use the smplayer to watch WorldTV.

1) Open>Playlist... and open 99TV4IT9d.m3u.
2) Options>Playlist and click any mms://, it will play. Description of the channel is an entry above it.

The reason why .m3u does not play because the first entry is a description line, not a mms://. That is why.

Please check out my favorite MTV station, kissTV, first station under Spanish, the only station broadcast on extended stereo.


Enjoy,
