OK I found the reason my iptv was not working was because I had a 
channel changer set (mythconverg.cardinput.externalcommand). This meant 
that the iptv channel (in dtvchannel.cpp) was never tuned and so nothing 
worked. The only solution I have found so far is a modification to the 
code. I may try discuss this with the devs the way it currently is makes 
it difficult to use any type of streaming set top box that has a channel 
changer.
