Here's a link for a thread on the Technical sub-forum.
http://www.satelliteguys.us/showthread.php?t=59177 The first post has a link to a document that describes replacement remotes, however, it does not get into details about original remotes, such as the 6.0.
Although you are looking for a 2nd remote so that you will have 2 remotes to control TV2, may I suggest that you consider getting a 2nd remote that could be used to control either TV2 or TV1 using UHF PRO. This way, if no one is watching TV in the living room, then the 2 bedrooms could each watch a different satellite program; 1 bedroom using TV2 output (maybe channel 63) and the other bedroom using TV1 output (maybe channel 61).
I don't know if the 6.0 will do it or not, the 6.2 and 6.3 should be able to, but you need the complete set of tabs to program/switch the remote to work.
