Thanks for the help. I deleted all channels and rescanned again. I lost 
one multiplex of 3 channels but other channels came through. 
Interestingly this was one of the channels where the frequecies were not 
changed and was retained the last time I did the scanning. Perhaps the 
signal was weak and it did not pick up while scanning.

All my scheduled recordings are in order and it seems to record 
correctly. But when I go to 'Watch Live TV' , it flashes for a second 
but does not show live TV. I wonder if it is trying to tine to the last 
channel that I watched which was deleted.
