A few weeks ago I adjusted our Netflix Instant Watch streaming quality to the medium setting. My ISP doesn’t have a data cap, at least not yet, but I figured it might not hurt to conserve bandwidth.
Today I logged in and changed it to the lowest quality setting. It’s possible that the Apple TV is ignoring the setting, but as far as I can tell the quality is actually still good. I’m going to try leaving this setting in place and wait to see how it works out. Going from the medium setting estimated to use about .7 GB/hour down to the low setting of .3 GB/hour may help keep our video streaming under our ISP’s radar, which is a greater concern now that we use video streaming in place of cable/satellite TV.
Last week I reduced the quality of video from Hulu, though it had less to do with conserving bandwidth and more to do with the fact that our Tivo seems to have trouble maintaining the Hulu stream from time-to-time.
Updated 10/09/2011: I’ve been using these settings for several months and have hardly even noticed a difference.
