Thank you for using our answers forum! I'm sorry to hear you are experiencing issues with your Slingbox Tuner. If you believe it is a firmware issue, I would recommend hard resetting the Slingbox to factory settings, then going through the setup assistant again. This will ensure that it has the latest firmware version. Also, our legacy SlingPlayer is no longer supported, however it is still available for download and should work with the Slingbox Tuner.
Below is a link that will take you to the download. Feel free to reply to the post if you run in to any further issues.
Hope this helps!

I noticed the SB220-100 has no input choice other than "cable in" w/ no cable box.
I would think since it also receives off the air NTSC channels, an off the air or antenna
input should be a selection too in the setup mode??? I need it to find NTSC off the air
channels and my other SB220-100 does find them and has for years and works great ???
