When the movie starts it loads no problem but the picture is slow or jumpy. I guess the best way to explain it is playback is in slow motion. Only the picture is. Sound is fine and is normal. So far the only way I have been able to sometimes fix this is by reloading it or hitting the refresh button several times until playback is normal. That does not work all the time. Have also tried closing and reopening my browser, restarting my computer, etc. Does this on any netflix movie not just one. Only on that site. Can watch movies on youtube as well as crackle with no issues. So this makes me think it is a Microsoft silverlight issue since that is what they use. All of my plugins and extensions are up to date and say they have no issues or errors. Lastly this only happens when I use firefox. If using internet explorer or google chrome everything is fine, but personally I do not like these and would prefer to use firefox. Any thoughts or ideas?
