I have not noticed any problems, I'm using a VIP722 and a serial-connected 
"MyBlaster". The MyBlaster is extremely reliable, but is no longer available,

Have you had any problems changing channels with the "official" DISH 

Has anything in your environment changed? Perhaps a new lighting fixture? 
Have you changed from incandescent to CFL lamps? Changed the curtains or 
blinds in the room? Is there a difference between day and night
