In our testing, some of the HDTV devices became unstable when the input type was switched from TunerInputCable to TunerInputAntenna or vice versa. Some drivers worked properly after the application restarted, but others required to be reset.
To reset the device's driver follow the steps below:
Reset the USB TV Tuner device by unplugging it and then plugging it back in.
Restart the computer for all other HDTV Tuner devices.
Additionally, note that HDTV device drivers perform better in Windows 7 than in Vista .
For HDTV tuner devices, LEADTOOLS Multimedia supports ATSC signals only.
For HDTV tuner devices, LEADTOOLS Multimedia does not support DVB signals.
