Thanks, this worked. I had already created a very similar XML file and registered it, but with my file I still got the 'not available' message.
Anyhoo, I must say I'm not impressed with the whole Internet TV beta. Now, I can't comment on the 'series' they offer as they are blocked by some sort of geo-filter, but the rest of the content were really low-def in my opinion.
Also, when I selected NBC Nightly News (I much preferred Brokaw to Williams) I expected to see the whole program, not just badly cut selected segments :(
The same goes for selecing Entertainment/Channels. Sure, I didn't expect them to have live feeds of CBS, NBC, ABC etc but I did expect to find a complete airing of The Today Show or other topical programming, but no, again they just have a selection of clips.
Nah, I'll stick with my current setup for now, which is TV-series grabbed via torrents (and DVDs) and newscasts are streamed live directly from the appropriate website.
Thanks though, for making a working xml file available.
