I missed something; when you press a button on your remote, does 
anything come out of the ir transmitter on the USB-UIRT box?  On my 
UsbMce box, it has an external blaster extension that's taped onto the 
cable box and flickers red when I press a button.  Either you see the 
LED flicker of the external blaster, or use a digital camera to see the 
ir signals.  If you see a flicker, we talk driver (i.e. protocol) and 
config; if not we look upstream.

...and yes, remote control issues are very irritating.

These are similar to the box I have:
