I understood the underlying cause to be Myth using local time and that question has been beaten to death several times on this list so I don't wish to resuscitate it!

It seems a very common problems with PVRs & TV receivers generally, I've never owned a PVR or STB that didn't barf twice a year and those sorts of forums are always full of "My Sky Humax, Topfield, Panasonic PVR+- ate my hamster's recordings" stories twice a year.

Half the broadcasters seem to be amazed and shocked that DST has happened again and I'm sure they will be equally surprised in October ;-)

Oh right, I get that from EIT too, was just wondering if I was missing something interesting?
