Ok, with current CVS...changing channel segfaults whether the channel
moved to is on same multiplex or not...however I have a small patch that
improves it to only segfaulting when moving between multiplex.  That
patch just deletes the decoder and creates a new one on channel change. 
But there is no point submitting it here now until I get it not to
segfault at all.
