Hi all, I have purchased a digital modulator to send paytv to all our tv's via our antenna. I had a faultless setup previously but was upgraded to a new fox box so the rf modulator wasn't up to the job.

On our tivo it picks up the pay tv channel but all it displays is a blank grey screen and no audio. Is this a limitation of the tivo itself, am I missing a setting or is it no go?

Thanks in advance
