Jaxson: The really annoying thing is this situation exists simply because freeview do not broadcast EIT data on their terrestrial service.
Sony could also do their part and adopt MHEG5, an open standards protocol which is now used as the primary EPG format in a growing number of countries including Australia (Freeview), the UK (Freeview) and NZ.
The MHEG5 NZ specs are available freely from Freeview and if every other company producing gear can build in support why can't Sony be bothered doing this?
