I'm a bit disappointed by the firmware upgrades from QNAP. The new 4.0.2 is fine for me, but the HD station feature of my TS 469L is shirt. There are some driver issues from intel causing issues is displaying videos in XBMC.
Would assume it would be high priority, but it is already a problem for a half year now.
We are also still working with XBMC 11 instead of 12.
