Thanks SatelliteAV.
My Fortec Lifetime Ultra: boot ver 6.1, Nov 1, 2004. Normally I use USALS, but maybe some of satellites I setup early may still have 1.2 setup. Do you think mixed USALS and 1.2 can cause problems?
I think the receiver can store the info now. What I did is that:
1. As I don't want to lose my setup info, I didn't do the factory reset.
2. delete all the channels for all satellites.
3. delete all the TPs but 1 ( it is good to have a live one, but not required) for all satellites.
4. Do the power scan for the Satelltes.
When I was deleting the TPs for each satellite stored in my receiver, I find a lot of TPs are not alive. The reason my receiver can not store my satellite setup is , I suspect, that the receiver doesn't have big enough memory, so the info I entered is lost. When I deleted unused TPs, I release memory space for the info I enter. This is jus I guess, but I do solve my problems any way.
Again, thanks for your offer help, SatelliteAV.
