JVine,

You might contact your cable operator to see if the cable box needs an update. I've seen several threads on this issue solved by that.

Otherwise, it could be a handshake issue with the Sony HT-CT100, in which case, you might want to update the firmware at this link:

Otherwise, it's a handshake issue with the HT, which I don't have the ability to provide support for that.

Keep me posted.
