Updated my box on Saturday night , reset it to defaults , no problems till watching home alone on Sunday night approx 7.05 , then the picture froze , switched to analogue tv and it was ok , switched back & still frozen picture , switched channels and they were ok , back to channel 5 and still froze , powered off box with the switch at the back and re-powered up - still frozen !!! , under pressure from kids now so watched end of film on analogue then switched back to humax and now picture ok , was able to rewind to when I switched box back on and could see the frozen part , it must have froze for 10 mins. any one else had this ?
