Ref,
You're right the Viewsat library of satellites, while pretty good, is hardly complete. I've been hand-loading satellite info, transponders, etc. and have added a bunch--mostly TV "live shots" and other feeds. I don't have a list exactly; I've just been using Lyngsat.com and a few other sources. If a get a few moments (

), I may try and download the channel management software from Viewsat, but so far I've just been punching things in by the remote.
Good luck,
Bob
