I am also looking to do this... What I want is to be able to show the playlist items from a UDP stream onto a HTML webpage, and then using JS making the playlist items clickable to change the channel.
Which do you want ?
A. a select lists, choose to select the one you want to play.
B. a preloaded channel list, click 'next' or 'prev' to play. (I've write a sample for this)
C. items with check box, click to pick some, then do what B. is doing.
