Hallmark Drama channel IP only?

In September Comcast added the Hallmark Drama channel to the HD lineup at 1460 (Sellersville PA channel lineup). After re-running the TiVo guided setup the channel was still not visible in the channel list. In fact; the channel list shows 1459 and then goes directly to 1462. TiVo support told me to contact Comcast, and Comcast said I cannot see the channel as it requires a new cable box with XFinity X1 at an additional fee. After doing some research, I found out that this new channel is IP and it will not be visible on a TiVo using a cable card. Assuming this is true, what other channels are IP only that I will not be able to see? Is there a master list somewhere?
