I am up and running for the HR20 thanks to some charitable offline help. I used an Elk serial to USB cable which indicates that it works with more than the three specified cables in the DirectV document.

The problem I am having is that the channel up and down and the directional buttons are sluggish. For instance when I hold one of the channel buttons only one channel will change. By doing this through IR a number of channels will begin to change. I played around with the ramp speed but was not successful. Was wondering if someone could point me in the right direction to hopefully fix this.

Thanks

Pete
