Found another fault in the Humax that seems to be persisting so I'm sure this is a design / coding problem not a unit specific problem.
When searching the epg for programmes later in the day (by using the navigation wheel to move to the right along a channel's timeline away from the current time usually only by one or two programmes so still on the current page), I'm finding that sometimes after pressing the back button to return to the current time, when I use the down side of the wheel to move down the channels on the epg, the cursor jumps back to the position it was last on, on the right of the epg and scrolls down from there instead of staying in the current time position on the left. This happens repeatedly and can only be alleviated by moving the cursor manually to the current time position by using hte left hand side of the wheel before scrolling down further. This quirk is intermittent in nature athough frequent.
