As cactikid has said, any good E2 box, the cheapest is a single tuner miraclebox with a cable tuner.
You have probably spent about the same in total that the miraclebox costs, trying to fix the problem.
They also do a combo, good boxes in loads of ways.
Better build quality, any updates can be done over the net direct to the box, good EPG,
EPG and channel list updates are done automatically in the night when the box is on standby,
good support.
I would say you are better off with a box which runs a genuine Vix image from world of sat, but lots are using the cheaper Zgemma's
As you have probably found out, you get what you pay for.
