Yep. That's a lot of wasted bandwidth.
For those HD channels that have a 3 digit and a 4 digit channel, those channel numbers are just aliases to the same stream so they're really not wasting bandwidth. If you haven't found it already, there's a menu setting to not show SD channels if there's a corresponding HD channel. So instead of seeing channel 105 twice, for example, you'd only see the HD version of it. I also suggest taking the time to set up a Favorites list to get rid of all the junk channels...
EDIT:
Here's how to hide the SD channels. I grabbed these instructions from another website and I'm pretty sure they're correct:
Press MENU, select SYSTEM SETUP, and then LOCAL CHANNELS
Select CHANNEL DISPLAY
Select HD PRIORITY
Select ENABLE
Select DONE
I definitely remember the LOCAL CHANNELS part and how stupid that was since the fuctionality has absolutely nothing to do with local channels...
