I just burned copies of the Australian DVDs of MI-5 Series 7, and it astounded me, as the density of each hour-long episode was almost 4.0 GB!! (Regular DVD, NOT Blu-Ray. What exactly determines the density of this? Why are some hours only 1.4 GB, 2.5 GB, or mostly 3.5 GB (good BBC DVDs)--why the huge disparity? And what does it all mean? I know denser is a better picture, but really, 4.0 GB of this Australian transferring/pressing compared to what will be the British or American version of the series that comes out next year at 3.0 GB per hour. Some rational explanation would be appreciated.
? That's not what I am asking. Of COURSE the disc was double-layered. I am asking why is an hour of televison 4.0 GB when typically an hour on US DVDs is anywhere from 1.400 to at the most 3.750 (and those mainly British DVDs. What accounts for some 1-hours being produced at say 1800, and others at 3750, when they look generally the same on a 54" TV. When this show comes out on British DVDs, the size of the hour will be 3.0 GB. And the 3.0 GB looks no different on my TV than does the 4.0 GB hour-long show.
I'm still not sure what you're talking about.
Are you inquiring as to the bitrate on a commercial DVD,
or some disk that you burned?
In any event, for an hour show to take up 4GB of DVD space,
it must have an average bitrate of about 9000 kbps, just about
the max according to the DVD standard.
At that bitrate, you could, of course, only put 2 such episodes
on a DVD 9.
