Connecting to Telvue

I am currently working on a roku channel that needs to connect to a telvue server. So far I have the live streams running smoothly, but at this point I am not sure if there is a way to grab all the content on the server. I know that you can put an xml file on the server and just read the information from that, but I was hoping there was a more dynamic way to grab content because new things get added regularly.
So my two big questions is 1) how do I connect directly to the server? 2) How would I then parse all the content and display on the roku. I know that this is a lot, but even little hints would greatly help in the process.
