Having read good reports from 'Which' I purchased a Humax 9150 from Richer Sounds. It was a display unit and came without a manual although the protective film was still on the front of unit so assumed it would be ok. Tried to used Auto channel search several times. Most channels were there except BBC & ITV channels. On investigation the signal on BBC was weak but it was BBC Midlands & I am in London reception area. I tried going to default settings but I knew would include an auto search. This worked and all channels were fine. However having set up m/c to record various programmes it failed to record some of the programmes and later on while recording the m/c froze. It also froze the next day and failed to record any further programmes until the m/c was turned off at the mains. a message appeared when turned on again which read 'Loading version 4.7' Has anybody got any ideas please?
