Sorry to hear about your experiences. For the record do you have the old (larger box with HDMI lead) or the new version (smaller with no lead)? I have the smaller and this is the latest.
I bought this with the expectation of some problems. Early software is never right and I wouldn't recommend you play with the system. Up and down the channel menu seems to be the most stable. I got a top-of-the-range HUMAX box for downstairs and that locks now and then. A cold reset will solve most problems in both cases. Not making excuses - but a fact of life.
You don't need to do a factory reset to get back the lost HD channels. I save them as favourites so I can get them via the heart button. A cold start (turn off at the wall) gives you the best chance of a successful return.
