What times are these shows on? Are they on at the same time, or one right after the other?
There both on at the same time (9pm). The DVR's firmware should be able to figure out that it's not recording anything before 9pm, but it (DVR) must think there's something it's recording before 9pm and ending after 9pm to produce the "clipped" message. If the DVR was recording something say like 8pm to 9:01pm, then it would display the clipped message, since there's a one minute overlap for one tuner to handle, which is impossible to record because the other tuner is recording the other program that starts at 9pm.
