it's actually not on-command, it's the TV manufacturers.....there's a long technical reason but let's see if I can shorten it...the remote is read by the TV which then passes the remove signal back to the On-command box on the back of the tv which then passes a signal back to the TV or to the On-Command system as appropriate....1 Manufacturer has integrated the box into their TV's (I believe it's LG but not 100% positive) and as a result has a very very quick response time when the remote is pushed....while you didn't mention the TV brand name IMO Philips has to be one of the slowest out there
