<h3><a name="Editing_TvTuner_Information"> </a> Editing <a class="twikiLink" href="TvTuner">TvTuner</a> Information </h3>
Sometimes in the recording process and the configuration process, you'll need to define and select tuner channels to either record or play back to. In the case of the Video4Linux and Buz recording drivers, tuner channels define the source. When the Buz driver is also used for playback, tuner channels define the destination.
<p />
Defining tuner channels is accomplished by pushing the channel.png channel button. This brings up the channel editing window. In this window you add, edit, and sort channels. Also, for certain video drivers, you can adjust the picture quality.
<p />
The add operation brings up a channel editing box. The title of the channel appears in the channel list. The source of the channel is the entry in the physical tuner's frequency table corresponding to the title.
<p />
Fine tuning in the channel edit dialog adjusts the physical frequency slightly if the driver supports it. The norm and frequency table together define which frequency table is selected for defining sources. If the device supports multiple inputs, the input menu selects these.
<p />
To sort channels, highlight the channel in the list and push move up or move down to move it.
<p />
Once channels are defined, the source item in the record window can be used to select channels for recording. The same channel selecting ability also exists in the record monitor window. Be aware channel selections in the record monitor window and the record window are stored in the current batch.
<p />
For some drivers an option to swap fields may be visible. These drivers don't get the field order right every time without human intervention. Toggle this to get the odd and even lines to record in the right order.
