My television has an A/B button which cycles the television from "TV" to "Video 1" to "Video 2" to "Video 3" and back to "TV", etc. Is there a way to have the RM-AV2100 make the television go directly to "Video 1" regardless of which setting I start from? In other words, can I set up a macro that will change the television to the "Video 1" setting, starting from the "TV" setting or the "Video 2" setting or the "Video 3" setting? I fear not, since the A/B just cycles the setting forward. Any ideas? Thanks. (I need this capability in order to simplify switching between TV watching, video watching, DVD watching, game playing, etc. for my wife and mother.)

Depends on exact what brand of television you're talking about. If a Sony, such codes are built-in. If some other brand, those codes may exist but the AV2100 doesn't have them (you may be able to "borrow" them from something like a Cinema 7 remote). Otherwise, you can try a workaround -- such as hitting CHAN+ to go always back to the TV tuner before sending XX number of video input commands.
