Live feeds are often ephemeral, i.e once you have done a frequency / Sr search and downloaded them into your receiver,they have disappeared.
A channel list such as that at Lyngsat's often show frequencies that are used for feeds.
Data channels by their nature are not normally video feeds.
Try a scan of a satellite known to transmit feeds, e.g. 7E or 10E.
