Mr. Pittaway is correct.
Basically you have to look at it in two parts. The first part is using the xltv plugin and integrating it to work with your card. Which the instructions in the link above should outline (been a while since I looked at it).
The second part is to integrate the plugin within Xlobby. This is done by either modifying an existing skin, or building up your own. My suggestion is to use an existing skin and change it accordingly. I think, this is the point your at. The key thing here is understanding the Setup/Events window. This is where you create events and tie commands to them. Commands are grouped together, so the group you'd be most interested in is the plugin group most likely.
The other thing to skinning is understanding the Pause/Break Skinning window, and attaching events to buttons.
There are four documents that you should read up on:

This guide will teach you the fundamentals of skinning in Xlobby.

This is a list of commands that can be used in Xlobby. Very handy for the avid skinner to have open while working on their skin.

Though you may be beyond this, it is still worth a read.

Though this guide is geared for Buddabing's KISS skin, it has some great tips that can be associated with any skin
The last bit of advice, play around. Learn how to create events by adding commands, then open the skin editor and applying these events to a button or category. The other thing, look at skins that have things that your trying to accomplish and see how those skins have tied things together. Basically, I think the French Team put together the xltv plugin, look at one of their skins to see how they have used it. I also think Buddabing has used it in one of his skins, so again, it may be worth looking at how it is used in his skin (Buddabing has great skins to learn off of).
Hope this helps.
