Al,
Yes, I have been reading the convergence proceedure on it, and I think I do
need to adjust the Horz, and Vert size controls on the sweep module, before
starting the proceedure. I have noticed that the picture seems to be too
wide, and also too tall.
With the DishNetwork guide on the screen, some of the info is off the screen
in all 4 directions.
I think you are right. I'll let you know.

Thanks,
LLW
