Boot to LiveCD, find my USB HDD already discovered, find driver install app, install the system, reboot. Sigh, HDD is still there. Install drivers, download 100+ updates including new kernel, reboot.
Try playing a movie. Alert appears saying codecs are not installed. OK, let's install some codecs then. And here's the part I don't like - the scary "Restricted app" message. While I don't really care about it I know 100% that any average user will be. And that will be an end for the media playback for him if some geek won't come and set it up for him.
Next stop - install Amarok, it being quite good media player. After installing it and building my collection I tried playing some MP3 files knowing what to expect - a pop-up asking to install MP3 codec because it's "restricted'. Boo, scary. Instead Amarok hanged... Restart, select a track, click play, boom, hang again. This time I actually see the pop-up but without any text or buttons. After a few seconds I am told that KNotify crashed.
