you can do some searches in the archive of this forum, because I think this was done back in software release 2.4:
Set up the first lineup properly;
Change your area code to a convienient second number (see next step);
Set up the second lineup with a similar but different lineup -- say your cable company also provides service for a town 20 miles away, under a different name, but with a similar channel lineup. Choose it;
Change back to your original area code.
Like I said -- the process you do this is hazy -- I remember we used to have to trick ReplayTV into thinking we were using different lineups. maybe my memory of this working back then isn't correct.
