SciAtl Explorer Remotes

Hi, I can't seem to find any information on this subject and I was wondering if someone might be able to help.


I have two Scientific Atlanta cable boxes on one tv - an Explorer 3250HD (high definition) and an Explorer 8000 (DVR, non-high def).


The problem is that they both use the same remote codes and so I can't operate them independantly. I push channel up, and they both channel up.


My only concern is that if I am using the HD box, I may inadvertantly be controlling the DVR box and modifying my recordings.


I used to own a Tivo, and it had an option where you could assign a remote number to a remote and to a particular box. Remote 1 would go to tivo 1, remote 2 to tivo 2, etc... Do the Explorer boxes have such a feature? Perhaps undocumented?


Thanks,

Matt
