MythTV Configuration

Setting the Default Transcode Profile

Navigate to the web page for your HDHomeRun Plus. On Mac/Linux, open a terminal window and run: hdhomerun_config discover This will display the device ID and IP address for your HDHomeRun; enter that IP address into your web browser. Click on Transcode Configuration. Select the preferred Default Transcode Configuration

Currently, there is no specific support for the HDHomeRun Plus in MythTV but it will function similar to an HDHomeRun Dual. (See the configuration instructions for that device.) The exception is multirec if you configure the HDHomeRun Plus to enable transcoding. Since the HDHomeRun Plus is only capable of transcoding one stream per tuner, MythTV can only record one (1) program from a stream. Thus you must set the number of virtual tuners to 1 for an HDHomeRun Plus if you configure the device to transcode.
