In order to perform this type of recording, you will need to install one of the latest version of the DVICO recording software (3.5 is recommanded, I am still working on adding support for 3.6). You might need to consult this thread in regard to some msvcrt71.dll errors when shutting down the DVICO recording software. You need to go to the web admin in order to create a new unencrypted QAM channels lineup (or use the "save as new" option on an existing one) and to hide all the encrypted channels. You also need to associate this unencrypted QAM channels lineup to the channels expected by the DVICO recording software through the Table of Channel tab.
The first step consist in selecting the capture device to monitor. To do that, use the drop down box and press the "Associate" button, the capture device will be shown at the bottom. Next, you need to enter the full path to the database used by the DVICO software to schedul recordings. You do need to keep BTV-Externinator and the FusionHDTV tray application running, in order for those recordings to happen. Support for the DVICO software version 3.6 is still in development...
