Basic EPG data is freely available across Europe and Australia via the DVB stream, but as @damstas mentioned, this does not include always include metadata (like season/episode number and original airdate) which is required to build a DVR (for instance, if you only want to record new episodes of a show).
The DVB stream also does not include any images, which makes it tough for us to implement the rich visual experience we are aiming for with Channels. There are a few companies which provide metadata and images, but as UK users are well aware the accuracy can be very hit or miss.
Rest assured, we are spending a lot of time looking into this and want to provide our international customers with the best experience possible.
