I’m having issues with the reliability of streaming which I know would probably be helped by some Roku device, still I’m not sure why if my computer can do the same basic things.  The latest Roku Ultra (4802R) has a quad-core processor, ethernet, operational memory of 2 gigabytes and a channel storage memory of 4 gigabytes.  See this Roku developer page for specifications on the devices and TVs.  Anyways I got through Doc Hollywood with some waiting, reloading and trial.  Some classic lessons in this movie and one I don’t remember exactly starring an example from my heyday, Michael J. Fox.  If you haven’t heard of him, I guess you are too young for me.  I keep thinking I am going to try to live in the past this way, but it’s like I’m peering through the bars with a new perspective from a different patch of grass.
