OK, I have my CX777ES up and running just fine via RS232.  Now I am trying to get DVDProfiler/LoadDVD to send out Ir to my Sony CX875 300 disc player.  I have set up all of my Ir commands and they work just fine via the command line window.  When I try to have commands sent through LoadDVd, I get: USBIRT not recognized as an internal, external command or batch file.

I have CX777 as the default player, and I have also checked the "Call USBIRT" in the LoadDVD setup.  In my "location" I have either rs232 or usbirt (depending on which machine the disc is in) and the corresponding track and chapter numbers.  It does not matter if the Ir is spit out for and rs232 disc in the CX777 since the two machines do not have the same Ir commands.  My begining batch file is as follows:

@echo off
"C:\Program Files\DVD Profiler\Plugins\LoadDVD\uutx -fcx875ir.bat" enter

rem send slot#
SET mynumber=%4
:NEXTNUMP4

set onenum=%myNumber:~0,1%
"C:\Program Files\DVD Profiler\Plugins\LoadDVD\uutx -fcx875ir.bat" %onenum%
@ping 127.0.0.1 -n 4 >null

SET myNumber=%myNumber:~1%
IF NOT [%myNumber%]==[] GOTO :NEXTNUMP4

I have tried both my uutx program and the file cx875ir in the LoadDVD filepath, and also put them both in the C:\ area - it did not matter where it was, same error of unrecognizable came up.

Hopefully this is a dumb error on my part versus - "Are you crazy? You can't do that". (Mediadogg, hope you're not laughing or discusted - I have read threads over & over - I just don't get it).
As always, thank you or anyone for solution.
