Tired of unwatchable programs

Tonight I was trying to watch Clerks on 247 NEXTHD.  It was not watchable.  When it did play it often was in blotchy mode.  It even BACKED UP and repeated something from several second ago.. 

Last week I was trying to watch a World Cup repeat on FS2.  You couldn't follow the ball, or the play, because it stopped every few seconds. 

I've had this service for a couple of years now and this is a new problem.
