Note that that information about the transmitted EPG format only applies to the new IceTV server. AFAIK, that's only used by the newer Beyonwiz T series, the Skippa, and perhaps some newer Humax models.
It's not used by the older Beyonwiz DP series, nor, AFAIK, Topfields.
The Season/episode information may be in the data from the older server, or not. It definitely is in the IceTV database, though.
