Try Channel 700 for the other satellite.
Whats the signal strength?
Should be over 80 on the older receivers, in the 90's on the newer ones.
If it's lower, you may need to change the skew.
What part of the country are you in so I can look it up in Shaw's Install Guide?
Corner Brook, Newfoundland
On HD such as NBC, channel 320... I have a signal of 75.
