Repeat delays such as this almost always aren't controlled by the remote, which are really simple things. The remote sends a continuous repeating pattern of a signal, and it's up to the device to determine how to respond to it, including deciding when to switch from "single action" to "repetitive action".
Usually when something like this happens, it's because the remote didn't learn the signal correctly - usually timings; ie. it may be playing it back too quickly.
Or, it could be some bizarre implementation of a toggle bit (when you said Philips I went "awwwww").
