I have posted the following with Humax support and am awaiting a response:
On three occasions now I have experienced a problem with the picture/menu transparency reversing so that picture is on top of text rather than the other way round. Each time this happened from the \"Freeview\" (Home Screen) menu and after selecting \"Media\" (two times) and Recordings (one time). The only way to get out of this condition was a power cycle (remove power completely) - off/on cycles made no difference. The unit is only a few days old and firmware up to date.
