Good value for great software with bugs

OS Win7 / 64bit. Installing TotalMedia 3.5 only works with USB 2.0 port.
With USB 3.0 with a NEC chip. Driver version 1.0.18.0. Station search stops at indeterminate point and freezes (no feedback). The green USB stick control LED lit permanently green. The Task Manager can not terminate the software. Subtracting the DVB-T Stick from the USB 3.0 port will see a blue screen.
Without bluescreen can just restart resolve the issue. But, Win7 is not shut down, remains under the Exit window available. Just turning off the computer stopped the disaster.
Errors can be repeated.

With USB 2.0 once the channel scan was performed and works perfectly. Channel switching works perfectly without crashing the software. Zipping permanent works.

After the scanned and saved channels, I have a test basis plugged to USB 3.0. Transmitter can be switched, after some time the software TotalMedia 3.5 freezes again.

One point deduction for the poorly written software. DVB-T Stick small and compact and works perfectly.

1 Another minus point for bad antenna. Almost no reception (2 ticks) just is not enough. Just feed cable 1 m long. To use remote control only nearby.

For better reception I built from a 1 m welding wire 1mm strong a pole antenna (similar to a metal coat hangers) and have it connected to a 5 m long coaxial cable.
5 ticks at the reception with all transmitters, mind you without amplification.
