I have Spectrum cable for tv and over the past 4 or 5 months I've had issues where the screen freezes for a period of time or the picture and sound breaks up.  I plan to call Spectrum about this but wanted to see if my problem is isolated or if others in this area are having the same problems.  Please let me know, if you use Spectrum, as to whether you are having these problems or not.  Thanks!
