We don't know yet what is triggering the issue. CF may not be required.Indeed, but if the options are >£100 for a new PVR or spend some time getting to grips with the custom firmware to possibly fix the problem and gain the extra functionality, the OP may want to give it a try.
On one forum there was some one who with an HDR-FX T2 who was having unwanted repeats recorded for some series (coincidentally for the channel 5 group) because of they did not understand how freeview series were organised. When a series had already started they were always selecting both the first broadcast and a repeat broadcast for recording, when all they really wanted was the series once and an individual episode from the repeats. Their explanation was that the search results were showing some episodes would not be recorded and so they thought they had to set series recordings for each result until all the results had a recording icon.
