David is having trouble with constant buffering with Netflix on his PS3. But it doesn't do it with subtitles. What gives? Rich says the first thing to look at is what has changed before the buffering began. Often, a change can cause those things. Rich also recommends going to FAST.com and test your internet speed. Rich also recommends uninstalling the Netflix app from David's PS3 and then reinstall it. Also, make sure that the PS3 is updated. Rich suspects that an update may not have been completely installed and uninstalling and reinstalling usually clears things up.
