Ever since Microsoft and CableLabs removed the OEM hardware requirement, the CableCARD tuner market for the PC has really heated up. While it has brought some new players to the PC tuner market,it is has also attracted some old favorites. We caught up with SiliconDust at CES and at that point the dual CableCARD tuner was just the test board (pictured above), but today the beta sign up went live. Anyone interested can fill in a few details about their setup and hope to get selected, but the response has been so great that we're told the window will probably be shorter than two weeks. If you are selected you'll receive the beta hardware in about four weeks. We would of course like to try it out for ourselves, at which time you'll hear all about it.
