Thank you for using our answers forum! I'm sorry to hear your having trouble with your SlingRemote. We may need some additional information in order to get to the bottom of the issue that you're experiencing here. Do you know if your TiVO/DirecTV receiver is set to receive IR signal? You should be able to find remote control settings within the menu which will allow you to switch between IR (infrared) and RF (radio frequency). As the Slingbox only uses IR, the box will have to be set to IR for your onscreen remote to function. Here is a link to an article from our support site regarding onscreen remote issues:
And if the issue persists beyond those troubleshooting steps, don't hesitate to give us a call:
Hope this helps!
