USB-UIRT will not learn in Girder 3.3.8

I need help using my usb-uirt to transmit an IR command to a VCR.
When I'm in the "Learn..." or the "IR Debug" diaglog in Girber for the USB-UIRT plugin, USB-UIRT does nothing. No Led flash, nothing is reported in any of the dialog fields. I've tried this on 2 different PC.
If a use the girder learn feature to get the hex code I wish to transmit and manually enter it into "Code 1", the "Test" function does transmit something (led indicator on seperate test device flashes) but does not control my JVC HR-S3902U VCR. Please help I can't figure out why. I tried 3 carrier frequencies (40, 41 & 56K) no luck. Know of any software that will capture this type of information for captured USB-UIRT signals.
