I'm now wondering if the lower resolution I experienced might have
originated at the DSHD network operations center, possibly during
conversion/encoding. It was constant and seemingly more significant and than
would have occurred from the lens issues you describe. However, I have no
technical knowledge of the Discovery Channel's operations.
