Hi.

I've been googling this PPPClear thing - It looks like it might be to do 
with the vdr-xine plugin.

http://linvdr.org/mailinglists/vdr/2004/11/msg00736.html
talks about multiple audio channels & a transfer patch in VDR 1.3.14

There might also be something in toggling the dolby selection in Xine?

I will try these tonight.
