I can't suggest when or if they'll be implemented, but I'll be happy to pass this to the appropriate department.
Thanks for taking the time to let us know about the features you want.
I enjoy playing media files; videos, music and photos being served from my PC and play it on both un46C7000 and un55c8000. There are some basic functions that I wish is incorporated with the system; (1) automatic refresh option (say every 2am). Refreshing huge DB files takes a long time. (2) Video cannot do fast forward or rewind continuously, skipping by chapter skips too much. (3) no background music option for photo slide show. (4) Compatibility with TVersity
Other than above wish list, both 3DTV are awesome!
