The bad news is that it can't be corrected. With the new HD GUI, the boxes cannot send out HD and SD simultaneously.
The good news is that you have two options: you can change resolutions to SD whenever you need to watch your distant display, or the better option is to get one of these converters:http://www.monoprice.com/products/pr...seq=1&format=2
(if it doesn't link, just search for item #7114)
This will allow you to connect the component out to the converter so you can connect it to your modulator and the boxes will believe everything is being distributed in HD.
This is probably the main reason that this particular rollout is so slow - there'll be lots of calls about this to CSR's.
