Observations:
HD channels are clear so does the SD channel, but the difference is visible
changing between channels take approx. 5 seconds to show up video, audio comes up live in 4 seconds.
RF remote has a nice range, it registers all the key press, sometimes while scrolling through channels, it double register. Thus sometimes it skips channels.
Box is always warm
Asterisk key [*] on remote shifts to different equiliser presets (works only for SD channels not for the Dolby sound)
