The problem with streaming movies over the web, or Television shows, (This includes Slingbox) is the bandwidth.. Most of the better video compression methods (If you want quality video) burn about a gig an hour.
Now if you are in a hotel with multiple T-level access and more bandwidth than you can possibly eat.. Slingbox is great.
I have seen some low-quality scemes at a quarter Gig and some very high higher (2 or more Gigs per hour)
So, if you are using park WI-Fi. you wont' be making friends, and if you are using your own cellular or satellite, you will quickly burn through your data alotment. Thus the best ways to view are this.
Rip a DVD or blue ray to hard drive and transfer to portable device
Record over the air (or cable or Sat) television with a DVR that can transfer to the portable device (My ReplayTVs do that, I have like 200 hours of movies stored on this comptuer can bel played on comp, tablet, android phone or streamed back to the Replays for viewing on the televisions).
Home was where I park it. but alas the.
