I've read that page a number of times, but haven't noticed this phrase until today:
"Today the main use for this new standard is the distribution of
HDTV, while the original standard was used mainly for
SDTV services. "
However, there is also this phrase: "The
transport stream delivered by DVB-S is mandated as MPEG-2."
So, it seems that while MPEG4 can be SD or HD
and MPEG2 can be SD or HD, DVB-S can
only be MPEG2. DVB-S2 can be either MPEG2 or MPEG4. Therefore you cannot use MPEG4 (SD or HD) with DVB-S - only DVB-S2.
