i have a dbox2 which i bought for a friend. now the problem is that when he tunes it in it finds 70 transponders but no channels. when i tune it in at my home i find 70 transponders and 303 channels. tried a starview and eurovox box at his house and they work perfectly. the funny thing is we have also tried another dbox2 and it worked. could anyone shed any light on this and should i contact the seller of the box.
