[mythtvnz] Freeview PVR specifications

[tortise]

http://www.freeviewnz.tv/media/9342/dtt_v2.0_dtr_spec_.pdf might be of 
interest, especially the highlighted new stuff, such as PVR's should add 
11dB to AC3 material to match AAC volume levels....

I don't think mythtv can be configured that way?

Also there is reference to a MHEG interaction channel that seems to be 
an Internet based line of communication.

Skip period functions are discouraged and not allowed to be less than 10 
minutes.
