Well i spoke too soon as far as the fix goes, and probably what the ultimate problem was as well. 30 minutes after i posted the above I was no longer able to get into the antennae setup screen. Every time i tried the Pansat would reboot. grrrrrrrrrr time to do a factory reset :-(
In replaying recent events in my mind, i remember that about 2 weeks ago the pansat was inadvertantly shut off while saving data from a blind scan (power loss due to windstorm). I think that corrupted something in the channel/ satellite lists which caused my problem, and it just took a while for me to notice it.
On the plus side a factory default fixed the problem, on the minus side i now have to re scan everything (30 sats, some both c band and ku band). Guess i know what i will be doing all day :-(
The one bright part of this is i am still using my analog reciever to move my BUD as i havent been able to hook up the vbox yet. So at least i didnt lose all my sat positions

.
So i guess i learned a valuble lesson, after today i will be using a channel editor to back up my channel lists.
BTW Iceberg, i am not sure how many tp's i had stored in the pansat total, several sats had 40+ tps for c band, and 40+ for ku band (due to multiple blind scans of the same sat). I know i deleted at least 300 tp's yesterday, with a LOT left in the pansat when it finally choked.
