I almost never use netflix on the road, I use an app called droidtv it allows me to download shows directly to my Android tablet or phone, both of witch I can hook directly into my tv if I want a larger screen.
I have a 32gb sd card in my tablet it allows me to store about 100 hours of tv on my device that I can watch anywhere even with no signal.
It's like $8 for 3 months service, and the shows are entire seasons including stuff that aired only the day before.
.
Jetflix also allows download to sd card but it's not as usrr friendly as droidtv's set up
.
I do all my downloading when near wifi and save my 4G cellular data for the rest of the internet
