Will I Get Better Internet If I Have A Landline? And Landline Costs?

[PoodMaiDai]

Some people have advised about 'streaming' movies and english speaking shows......in your experience is this going to work considering my situation ie .... Out in Chiang Dao ...away from town...hopefully with a fixed telephone line installed...?

It depends on what site you stream them from. Youtube uses a CDN so it should stream fine on a decent Thai internet connection. You find some obscure site that is just hosted in the USA with no CDN, it won't work very well for you.

Netflix won't service Thailand (have to use a proxy). Not sure if Hulu does or not, I do not use them.
