I've searched the forums for similar ideas, but I think what I want to do are slightly different. Let me know if I'm wrong!
I'd like to RF modulate the output of a security DVR onto my OptimumOnline digital cable network. Ideally, the channel would be viewable via both the cable box (SA 8300HD in the family room) and my cable-ready TV (bedroom), but I'm fairly certain that the cable box won't see an analog channel. To overcome this, I thought I would use the old VCR still connected to an aux input to the family room TV.
My problem is that I can't find any definitive information about the digital cables frequency usage. Can I insert a channel using my HMM-10H RF mod (CH14-CH83 or CH65-CH139) with an RF dist amp (HVM-1308) and the appropriate notch filter, onto the digital cable without interfering with digital channels or the cable modem? And if this works, will it still work after the digital changeover in June?
