One thing has been sorely missing since Media Center first became available in Europe back in 2003. That was DVB-T radio channel support, as right now Media Center isn't setup to be able to handle the data coming from these channels so they get blocked out during the channel scan. In Media Center 2005 the way tuner cards were handled changed. This allows them to be put into use when live TV or a recording is not in progress (where as 2004 'locked' onto the card for itself). This has opened up the TV Tuner hardware to 3rd party applications, and Hauppauge have released a beta application which allows access to DVB Radio services. The downside however is that currently only the WinTV Nova-T USB2 tuner is supported, although Hauppauge are expecting to add support for the rest of their DVB-T hardware in the coming months.
