I'm wondering if there's any difference between the IR that is sent from a TSU9400 versus the IR that is sent from an RFX9600.

First, some background information on my setup. I have a Xantech 791-44 connecting block. It gets its input from two sources:

1. A Xantech IR receiver is connected to the Xantech 791-44 connecting block.

2. The IR port #1 output (set to "low" output) of my RFX9600 is also connected to the same Xantech 791-44 connecting block.

Thus, my Xantech 791-44 connecting block can receive input from either source.

My devices are connected to the Xantech 791-44. I have a number of devices connected to the 791-44. When my TSU9400 is configured to send IR output for all the devices, all the devices work correctly; i.e. they all correctly respond to the IR codes sent from the TSU9400. When my TSU9400 is configured to send RF to the RFX9600, which in turn sends IR to the 791-44, most of the devices work correctly, except for two devices: my TiVo Series 3 and my X10 IR543. The X10 does not work correctly - it does not respond to any commands sent by the RFX9600. Most of the commands of the TiVo Series 3 don't work when going through the RFX9600 - either no response, or very intermittent behavior. However, when I configure my TSU9400 to send IR for the X10 and TiVo codes, they both work correctly and reliably. Thus, I'm wondering if there is any difference in the TSU9400's IR versus the RFX9600's IR.

Note that when using the same TiVo and X10 commands sent via RF using my TSU7500 and RFX6500, the TiVo and X10 work correctly.

Anyone have any suggestions why I'm having trouble with the RFX9600 (note that all other devices work okay, so it's not my RFX9600 configuraiton)? Does anyone control their X10 or TiVo via RFX9600?

Thanks.
