Well, the Hr44 works with the TV...
In these sort of situations, it's often impossible to say which piece of equiment is "at fault". But we regularly see situations where a set top box (cable and Dish as well as DirecTV) and an AV receiver have problems. Not that it's completely relevant, but I have an HR44 connected to a Sony A/V receiver and then to a Samsung TV and have no problems. And the same HR44 was connected to a Denon A/V receiver and then to a Vizio TV and had no issues.
Try leaving the HR44 on all the time and see if that changes things....
