Anyone experiencing sluggish channel selection? Also, I can lock onto the China, Japan and DW bouquet at 58 deg, but cannot see them (error- channel not available). Several bouquets exhibit this behavior or take a long time to show after selection. I refreshed all software update, reconfigured settings, rescanned channels, sync time to NTP etc. Then there is the random reboot......

Tried to tune in the channels you mentioned (i.e. CCTV, NHK World and DW) and they all worked fine over here using the currently released firmware so please try deleting the problematic channels then rescanning the transponders they are on.  If this still does not help, try rebooting your receiver.  On the rare occasion that you experience slowness in changing channels, please try turning off your receiver by selecting Shutdown from the menu then turn it back on.
