Looks like my concerns over the build quality of the I-Player are turning into problems... I decided to see what the signal strength & picture quality were like on the box when it was connected to an aerial socket being fed by an external aerial (as opposed to the internal attic aerial I've got), so I powered down the I-Player, unplugged it from my set-up and took it over to my parents place. I was a bit puzzled when, after having plugged it in and attempting to tune the channels, the box said it couldn't find any channels, but assumed that the aerial might well be pointing the wrong way or the signal might need the help of a signal booster as it does at my place. However, on returning home i found that the box couldn't be retuned in to the channels I'd had before. I tried auto-tuning a number of times, but the box wouldn't find anything whereas just an hour and a half earlier it had everything Freeview offers at the moment. Anyway, I'm prepared to give Netgem the benefit of the doubt this once and assume it's a duff unit. I'm getting mine swapped out by John Lewis, who were terribly helpful when I called the number on the dispatch note.
