THIS IS AN INCOMPLETE WORK IN PROGRESS
This article describes the Recording Profiles Setup page of MythTV Setup.
If your tuners supply the ability to record at different quality levels or to select other parameters, the parameters can be set up here. devices that capture the digital stream directly from digital TV do not allow much in the way of quality setting options, as they simply records the incoming data without processing it. Tuners that capture analog data will allow many options for how to encode that data.
Also set up here are options for whether to trans-code the video after recording, and parameters for how to transcode video.
For an initial setup you can ignore the Recording Profile setup and use the defaults. If you are using a digital recording device there will not be much to be selected anyway.
There are predefined recording profiles for each type of capture card
These profile groups are predefined in the system
| Capture Card Type | Recording Profile Group |
| DVB-T/S/C, ATSC or ISDB-T tuner card | Hardware DVB Encoders |
| HD-PVR H.264 encoder | HD-PVR Recorders |
| HDHomeRun networked tuner | HDHomeRun Recorders |
| FireWire cable box | FireWire Input |
| Ceton cablecard tuner | Ceton Recorder |
| IPTV recorder | Freebox Input |
| Analog to MPEG-2 encoder card (PVR-150/250/350, etc) | IVTV MPEG-2 Encoders |
| Analog to MJPEG encoder card (Matrox G200, DC10, etc) | Hardware MJPEG Encoders (Matrox G200-TV, Miro DC10, etc) |
| Analog to MPEG-4 encoder (Plextor ConvertX USB, etc) | USB Mpeg-4 Encoder (Plextor ConvertX, etc) |
| Analog capture card | Software Encoders (v4l based) |
| Import test recorder | Import Recorder |
| Demo test recorder | (none) |
| (none) | Transcoders |
In each Profile Group except Transcoders are defined these profiles:
| Default |
| Live TV |
| High Quality |
| Low Quality |
In the Transcoders group are defined these profiles:
| RTjpeg/MPEG4 |
| MPEG2 |
| High Quality |
| Medium Quality |
| Low Quality |
Card type: DVB-T/S/C, ATSC or ISDB-T tuner card
These capture cards are digital TV tuners, able to receive digital TV signals from various sources, such as over the air, cable TV or satellite. Different standards apply to different countries. Support for these devices depends on drivers supplied by http://www.linuxtv.org/. To determine if your device will be supported, visit the V4L-DVB Wiki. There are articles about each type of tuner in the relevant categories. For a description of the differences between DVB-T/S/C, ATSC or ISDB-T, search on wikipedia.
| Setting | Default Value | Settings Page's Description | Additional Comments |
| DVB device | List | When you change this setting, the text below should change to the name and type of your card. If the card cannot be opened, an error message will be displayed. | If Linux recognizes your device it will appear in the list. If there is nothing in the list you will need to investigate whether Linux supports the card and how to get it working. |
| Signal timeout (ms) | 500 | Maximum time (in milliseconds) MythTV waits for a signal when scanning for channels. | If it is missing channels on the channel scan, increase this value. |
| Tuning timeout (ms) | 3000 | Maximum time (in milliseconds) MythTV waits for a channel lock. For recordings, this value will be doubled. | If Live TV or recordings fail you may need to increase this. |
| Recorder Options | |||
| Max recordings | 2 | Maximum number of simultaneous recordings this device should make. Some digital transmitters transmit multiple programs on a multiplex, if this is set to a value greater than one MythTV can sometimes take advantage of this. | This is only useful if you have two recordings at the same time from two channels that share the same frequency. |
| Wait for SEQ start header. | Checked | If enabled, drop packets from the start of a DVB recording until a sequence start header is seen. | |
| Open DVB card on demand | Not Checked | If enabled, only open the DVB card when required, leaving it free for other programs at other times. | |
| Use DVB card for active EIT scan | Checked | If enabled, activate active scanning for program data (EIT). When this option is enabled the DVB card is constantly in-use. | |
| DVB tuning delay (ms) | 1 | Some Linux DVB drivers, in particular for the Hauppauge Nova-T, require that we slow down the tuning process by specifying a delay (in milliseconds). | |
