I found the exact problems mentioned in this thread. While upgrading to 1.00.07.601 made 1.2.0 beta work for me, the drivers are unfortunately unstable when using multiple tuners on the same box. This was never a problem with 1.00.05 on 1.1.3. I have had to disable one of the tuners for now, but am currently in a tight spot between 1.2.0 beta not working with the old drivers and the new drivers not working with multiple tuners.
Any chance of making a special case to make the old drivers work?
