This is interesting, I once lived in a Metro area, They had a netflix processing center in my area and my turn around was a day. More if they got the older DVD's from a different location. However, I moved to a rural area about 100 miles from the processing center and I am still at only 2 days turn around. To be expected !
I don't know why this would change, I have a rural P.O. carrier who I mentioned this too and he looked at me funny and said, " Not to worry". so, I won't !
I stream too but, not as much as most. Haven't had a problem out here in the boondocks !
