Hey Rick Hales,
Thank you for using our Answers forum. I'm sorry to hear that your having trouble with your remote. Are you talking about your actual Rogers remote that you hold in your hand, or are you talking about the one on your Slingplayer? The remote on your Slingplayer should work exactly as the one in your hand, including using your DVR controls.
If it is the one on your Slingplayer, you might want to try and reconfigure your remote, you might not have the correct one, but in fact one that is similar to yours.
Hope this helps.
