Advanced Settings
Here you can select the details of video and audio quality settings of recorded
programs.
Format: Choose between MPEG-1 or MPEG-2 video encoding formats. For
example, select MPEG-1 if you want VCD format or select MPEG-2 if you want
DVD format.
Dimension: Select the recording resolution you like.
Video Bit Rate: Video bit rate is expressed in kilobits per second. The higher
the bit rate, the more processing power and disk space are required to record
and playback video programs.
Audio Bit Rate: Choose the audio bit rate you like here. Audio bit rate is
expressed in kilobits per second.
Frame Rate: NTSC system uses 29.97 FPS (Frame Per Second) while PAL
system uses 25 FPS.
Variable Bit Rates: Checking this box will use variable bit rates to record.
Usually, this will have better video quality. However, CPU loading is higher as
well.
Audio Frequencies: Standard DVD audio frequencies are 48 KHz while other
formats use 44.1 KHz.
Lock current channel while recording: Checking this box will disable the
channel switching. Unchecking this box can change channel while recording.
Note
Switching channel while recording doesn't mean you can record two channels
simultaneously. Instead, it is to record another channel after the switch.
