Is it recorded correctly ? Just wondering !
Also, any command which can some how tell whats inside the
stream/program, bitrate, frames, resolution, total time, etc without
actually playing it ? Something like gspot in Windows.
FOX HD shows are typically around 6-7 GB/hour where I live. Fox uses 720p
which requires less bandwidth than 1080i.
ABC HD also uses 720p, but their shows are smaller where I live, because
they reprocess the MPEG shows to have a lower bitrate. They do this so they
can sell bandwidth to other companies and make some money.
Also, since Attack of the Clones was a movie to start with, maybe it was
broadcast as 720p24 instead of 720p60. (Movies are filmed at 24fps, so
broadcasting at higher refresh rates wouldn't add anything--it's only
done with NTSC since NTSC only allows one format.). If so it seems
sensible that 720p24 would take about half the bandwidth of 720p60...
