Hi Metropolis,
The TV Server log showed that both tuners continued until shutdown.
I'm thinking out loud here, but it may be useful to try watching one channel, recording a second and then recording a third and fourth so we can see via the TV server log what the tuner is doing. From the previous log the tuner was tuning to two different channels. Also, make a brief mental note of what you did and time and post this with the TV Server log as this will identify what the tuner is doing.
I would try Ray's suggestion first, and maybe try another PCIe slot if you have one.
