They told me that they couldn't inform their retailers because there are so many of them!!
What I don't understand is that the software version that was installed in the box I bought yesterday was, I think, May 2014, which meant that the WiFi dongle they included in the package didn't work with that version or 1.01.06. The Humax chap said they only discovered this issue about 3 weeks ago. I find it hard to believe it took soooo many months for it to come to their attention. Sounds like a bit of BS to me.
The other thing I found during set up was that if you attach an Ethernet cable, the HDR wont recognise it (and/or connect to the internet) until the device has been switched off and back on again.
