Very interesting -- the problem does NOT occur on Chromium! I have the latest Chromium ( Version 49.0.2623.108 Built on 8.3, running on Debian 8.4) and all videos I tried run perfectly... I also notice that the browser performance overall is snappier than Firefox, so it looks like I'll stick with Chromium -- although as another poster suggested that moving from the 32 bit version of Jessie to 64 could make my video performance better (as well as a possible switch from Gnome 3 to LXDE or Xfce) I may decide to make these changes as well. I didn't address your other questions, Sven, because this seems pretty conclusive -- but let me know if you're still curious about those things. Thanks! Harris |
