I've had many problems with my 9300, some of which later cured themselves, some of which remain (see other posts). Pretty sure they could be solved by formatting, but there's things on my HDD I want to keep, as they are very unlikely to be shown again (most notably Radiohead live at Reading, and Charlie Brooker's Screenwipe/Newswipe).
Its a great machine when it works, but if I had known its faults and limitations I would have bought something else. Seems strange that the 9200 would feature USB archiving, but the supposedly upgraded 9300 doesn't.
