time code log panel in CD time code mode, and hold down the [Ctrl] key for about 2-3 seconds to
continuously log time codes from the CD drive (*). Then add the time codes to the cue list and check
the time between individual time codes.
(*) It may be necessary to set keyboard repetition rate to max to log as many time codes as possible.
Preferences menu
View Track Info - Expand the control to show individual track time information.
CD Device Settings, Status Timer Interval - Set a rate between 50ms to 1000 ms or select minimum
(fastest) - default value is 100 ms.
Minimum depends on system, but is usually around 5 to 7 ms. The lower the value the more often the
time code is read from the CD-ROM, allowing for a more precise time code triggering of the cue list.
However some Windows versions/CD-ROM drive combinations take a very long time (25-100+ ms) to
return time code for the CD-ROM. Setting a low value on a 'slow' system may slow down the PC a
low, even to the point of choking the PC. The caption of the CD control continuously displays the time
taken for the last status polling - setting a time polling time at about or lower than the average polling
time will cause the system to slow down a lot.
Tests have shown that the way Windows 2000 and XP drives the CD-ROM drive seems much more
effective than Windows 9X (although this may not apply to all systems) - if CD audio is a crucial
element of a Windows 9X system and response time from the drive is high (50ms+), it may be a good
idea to upgrade the PC to Windows 2000 or XP.
Commands
Even though Microsoft has published a command interface for use of CD-ROM, not all Windows
versions/drive combinations seem to work according to the command set - if the drive doesn't work as
expected try set or clear the following options (by default all options are on).
Use Stop as Pause Command - The control issues a stop rather than a pause command (some drives
does not seem to recognize the pause command).
Pause before cuing position - Some drives ignores a position command if they are already playing.
Check this option to issue a pause command before re-positioning.
Invalidate Timecode when stopped - some drives return invalid or wrong time code when stopped
(which may cause the cue list to behave strangely). Check this option to automatically invalidate time
(set to 0) code when the drive is stopped or paused.

No Disc or Drive Not Ready
No disc is inserted into the CD-ROM Drive or system is still initializing
Cannot open drive tray
Some CD-ROM drives will return a tray-open status even when the tray is closed if there is no CD
present in the drive. On "Eject" LightJockey will try to "Close the tray that is already closed. Shift
click on the eject button to force the tray open if necessary.
Message: CDROM drive already in use. The drive cannot be shared between applications
Another application is already using the CD-ROM drive. Most likely it is used by the Windows CD -
Player (check in the Windows taskbar). Often this will happen when "CD insert notification" is enabled
on the CD-ROM drive, auto-starting the Windows CD Player application whenever a new Audio CD is
inserted.
There are two ways of fixing this problem. The first fix is to disable the auto insert notification. This
may be done by right-clicking on the "my computer" icon on the desktop. Select "properties" and
"device manager". Select "properties" for the particular CD-ROM Drive, and disable "auto insert
notification" on the "settings" tab. Please note that this will disable the auto-start feature for any CD-
ROM.
