Recording problems with Adaptec Dual Tuner USB Device

[rander]

Just installed the Adaptec Dual Tuner USB2.0 device on my 4.6 BTV server. The wizard recognizes both inputs on the Adaptec, but if I try to record two shows at the same time I only see one of them in the "Upcoming Recordings" listing. I was expecting to see both.

Does anyone else have the Adaptec Dual Tuner device installed and are you able to record two programs from the separate inputs at the same time? If so, I'd like to know how you did it.

My Adaptec device is connected to the USB2.0 port on the motherboard. Also connected to the motherboard is a Haupppauge USB2 device and my APC Battery backup unit. Internal to the system is a PVR250. All the other recording devices work well including one of the Adaptec inputs. As I said, I just can't get both inputs on the Adaptec to record at the same time.

By the way, after setting up the recordings I go into Recording Settings and Priorities and modify the input device for the two shows I picked to record at the same time.

Thanks.
