The tuner module should have come with a CD-ROM that includes the rock-solid, dead-stable, works-as-advertised non-beta version 1.03 software, along with instructions on how to install it and use it.

It is well known that 2.0 beta 7 has bugs. It also has an assload of cool new features. So until the 2.0 software has stabilized, you have two choices: Use the stable 1.03 version with fewer features, or walk on the wild side with 2.0 beta 7.
