Someone who has the RS-1933 could help you better to find the channels. However, that contains the information required to find the transponder and receive the channel. I am assuming that they are still active...
On SES-2 @ 87W on C-Band, the transponder is 4000 H 29125. If you have that Frequency, Polarity and Symbol Rate in your transponder list, then the channel should scan in for you, with the video ID of 4113 and the audio ID of 4352.
Likewise, on 97W, G19, Ku Band, the transponder is 12115 V 22425.
If these are not in your list, then you will need to add them to get the channel. If you need the manual for RS-1933, it is available online, just google for it.
