NO AUDIO RECORDED PROGRAMS

I'M HAVING MORE AND MORE ISSUES WHILE ATTEMPTING TO WATCH RECORDED PROGRAMS. WHILE WATCHING RECORDED PROGRAMS THE VIDEO WILL HICUP AND THEN  WHEN THE PROGRAM CONTINUES THERE IS NO AUDIO. THIS JUST HAPPENED WHILE TRYING TO WATCH "WASHINGTON' RECORDED FROM HISTORY CHANNEL. THIS IS NOT THE ONLY CHANNEL THIS HAS HAPPENED ON, REGULAR CHANNELS AND CABLE CHANNELS.
