Hi Biglad, mines been done, hd channels are running tonight without a single glitch, but sometimes the hd channels can be a bit glitchy, its a bit hit and miss, as usual check all your connections, turn off your modem, router or hub and leave it for about 30 seconds before switching it back on, when im not using the box i will normally turn it to standby and switch it off at the back & when i turn the box back on, i find that it will run fine.
