Take a look at the link below. I was a little skeptical at first but this device actually does work. It also has the advantage of sending the RF signal directly from your current remote. There is no need to take the IR signal from your remote, convert it to RF through a piece of hardware and then back to IR through yet another piece of hardware located "line of sight" to the IR reciever eye on the end device. The existing remote is modified so it sends both IR and RF signals directly. I have done the IR-RF-IR conversion before and it has always proven to be bothersome at best. Maintaining the alignment of the conversion hardware requires constant attention or it must be "nailed down" permanently to prevent any sort of movement. I hope this helps.
