Thank you for posting on the Sling Answers forum.
It appears that you may have chosen an incorrect option for TV Provider during Slingbox setup.
To remedy this, you can reset your provider and lineup on http://newwatch.slingbox.com/ under Settings / TV SERVICE.
Be sure to choose "Time Warner Cable - Digital", and not "Time Warner Cable - Cable".
Let us know if this does not fix your lineup issue.
PM @ Sling
Thank you for your response. I have gone to Settings/TV Service and the choice I made was "Time Warner Analog - Digital (Sumter)." Thereafter only 85 channels were located and I have the same problem -- namely the highest channel is 99 and I would like to watch channel 384 (the SEC Network).
I would be grateful if you would have another suggestion. Thank you again.
The only other choice under Settings/TV SERVICE/Configure Inputs for Time Warner (which is my service provider) is "Time Warner Analog - Analog (Sumter)". I just tried Time Warner Analog - Analog (Sumter) and now I only have one channel. I thereafter tried to reconnect to "Time Warner Analog - Ditigal (Sumter)" but now I continue to have only one channel (as compared to the 85 before) -- this is very frustrating. Please help. Thank you.
