From this comment I take it the other criticism (mainly 'duplicating existing tools instead of contributing to them') is valid? Or are there good technical reasons why it was decided to start all over instead of contribute to a project like Phonon or QtMultimedia?

Part of the design is DBus for license separation -- to use say Phonon with a bluray decoder you'll probably need a license exception (like GStreamer has) and I suspect Dolby approval would be impossible.

As I said earlier, the design is mostly based on real world legal and technical concerns for the target use-case (dvb, dvd, bluray, dolby) that no other projects cope with.

License-separation is an annoying concern from a technical perspective. But I wonder if the separate process can be useful for stability/security too. (I suspect stability: easier and security: hard, but I'm just guessing.)
