# stolen-from: Tunapie.sf.net
#
# As seen in Tunapie, there are still TV listings on Shoutcast. This module
# adds a separate tab for them. Streamtuner2 is centrally and foremost about
# radio listings, so this plugin will remain one of the few exceptions.
#
# http://www.shoutcast.com/sbin/newtvlister.phtml?alltv=1
#
# Pasing with lxml is dead simple in this case, so we use etree directly
# instead of PyQuery. Like with the Xiph plugin, downloaded streams are simply
# stored in .streams["all"] pseudo-category.
