I wouldn't know where to start with a pdf version. But yeah, both guides do need an update.
I was trying to talk the author of eac3to into adding dpl2 upmix to his program so it would all be one step and this guide would be pointless.
Other people weren't exactly clamoring for it so I wouldn't hold my breath. It's a bit of a shame since eac3to pretty much can do everything else.
