OK, understandable but an annoying 'feature'. In Freevo (www.freevo.org) we
have a TV channel list that includes different inputs. I.e. composite and
s-video inputs are in the same list as tuner channels. The user can 'zap'
through the channel list: BBC 1, Composite, S-Video, BBC 2, ... without
stopping the player (xine in this case). I'll now have to find a way to
re-enable this functionality. Restarting the player is not an option, that
takes too long.
