It seems to me like this is TWC's way of "forcing" the new graphics on the legacy STARs (the XL, at least). They know that the XL is much too old and outdated to receive any sort of graphics updates, so they just remove the presence of the LDL. I strongly disagree with the XL LDL being turned off, and it will never cease to amaze me how ignorant TWC is... I know a lot of people who are lucky enough to see the XL have complained.
Actually is quite capable of doing most of the things the IS can do. Brian has done a nice job making an ldl
Mike has a point. But if the warning crawls are going, wouldn't the National LDL still be visible? 
Yep, that's what I call a fail. You only see part of it. 
What do you mean? You always will see the ldl behind the scroll if its the big one. When a warning scroll is created it overlaps the ldl. Since they used to be the same size you didn't see it.
