OK,
Telstar 5 and IA 5 are the same satellite, they just renamed it.
Most of the channels you want are on the 12,146 MHz transponder.
You will need to enter this data on a new transponder (manual for the receiver will tell you how to do this):
frequency = 12,146 MHz
polarity = vertical
symbol rate = 22,000 ksps
Then do a scan of just this new transponder and the channels will come in for you.

Here are the channels available on this satellite; the ones in yellow with a little "F" icon are free to air and available with your receiver.
