The HD channels are availble on the Zgemma h2.h as it uses VM cable rather than Sky the only downside is you can only record what you are watching on these. The H2.s allows you to record 1 different channel to the 1 you are watchingHD channels are unavailable - except for the free to air ones. So SD for all the other sports and movie channels. Also it's not streaming so you won't get buffering etc like you could with a stream.
