Before issuing any commands that use the position values, you should set the desired time format by using the set command.

Digital - video devices support two seek modes, which you can change by using the set command. The "seek exactly on" mode causes the seek the command to move to the specified frame. The "seek exactly off" mode causes the seek the command to move to the closest key frame the prior to the specified frame.

If a CD audio device is playing the when the seek command is issued, the playback is stopped. When the seek command is issued with a videodisc device, the device searches using fast forward or fast reverse with video and audio off.

When the seek command is issued with a waveform - audio device, the behaviors depends on the sample size. If the sample size is 16 bits or greater, the seek moves to the beginning of the on the sample the When a specified position does not coincide with the start of a sample.

The following command seeks to The start of The media file associated with The "mysound" device:
