i have read a lot of the posts but my particular problem seems different. its probably not, so sorry in advance. my 722 running 7 will often stop buffering (grey line) on you tube. to solve the problem i click the play icon (red line) beyond the point where the buffering stops and wehey off it goes again, maybe about an inch or more in 1 second then stops again. this is an intermittent problem. i am looking for a rare and sought after creature to reply, that is, the geek genius who can speak in terms the techy retard can understand. this creature, i suspect, is mythical. thanks guys.
