For the past week or so, my Slingbox M1 won't send repeat commands to my STB. For example, I have U-Verse, so my HD channels start at 1000. If I try to tune to channel 1005, my sling box sends 105 to the STB. I can repeat this with any button (for example, trying to press OK consecutively while navigating menus). This problem exists with both the onscreen remote using the SlingPlayer app and with the handheld remote that came with my Slingbox. I have checked for software updates on my Slingbox and I've reset the Slingbox, but the problem persists. This is a recent issue. It previously worked fine.
