IMO a demuxer should not read config files itself. This is very bad
practice. Instead the DVB playlist code belongs at the playlist level,
in the player. The demuxer should just accept freq/etc. parameters
from the player.

Huh? It's not needed. Sometimes a url gives you a playlist (e.g. asx
streams) in which case that gets loaded by the playlist loader and
then played. DVB could do the same if it has a way of reading channel
info from the signal; I have no idea since I've never seen/used DVB.
