How much MB in internet would a 20 minute TV show use up on average and how many MB would it use on my iPod?
A 45 minute TV show is about 200 MB for SD and 600 MB for HD. See:
How do you know if it is in HD or SD? And would it make ANY difference for use just on a iPod touch?
So 200MB for 45 mins, that's about 88 MB.
The 4G is the only iPod that can play HD.
The iTunes store ays if it is HD. If you hado not ha as 4G, it will only transfer a SD to the iPod.
I have a 4G, but i only want a SD. How do i just download SD?
