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.
Switching channel while recording doesn't mean you can
record two channels simultaneously. Instead, it is to
record another channel after the switch.
