TitanTV, USB-UIRT and Set-top-box

Hi all,
This is a rather obscure although not totally unique project/question.
I have a USB-UIRT and Girder. I want to be able to click on 'Watch Now" on the Titantv guide and have the USB-UIRT blast out the channel change to control my Directv box. I do not care about scheduling recordings. I don't even have a PVR/Capture card in the PC.
The file that comes from Titantv is a tvvi file. In notepad, it looks like this:
<tv-viewer-info version="1.0">
<program>
<station>NGC</station>
<tv-mode>satellite</tv-mode>
<program-title>Dog Whisperer</program-title>
<episode-title>Skyler, Cassie & Tori</episode-title>
<program-description>Tori, a compulsively spinning miniature schnauzer, is attacked repeatedly by her two playmates Cassie and Skyler. Also: a quartet of misbehaving French bulldogs; a rescue dog from Atlanta.</program-description>
<start-date>20070818</start-date>
<start-time>15:00</start-time>
<end-date>20070818</end-date>
<end-time>16:00</end-time>
<duration>01:00</duration>
<rf-channel>276</rf-channel>
</program>
</tv-viewer-info>
As you can see, toward the bottom is the <rf-channel> which shows 276 (the channel I want blasted out the USB-UIRT). For my purposes, all the other information is irrelevant.
Unfortunately, I'm not a programmer.
Is there any way, when I execute this tvvi file (clicking on 'watch now') that I can have the correct blasting occur?
