Most playback speeds do not seem to work correctly with Windows 2000 SP2. Note that The Observer XT (and higher) does not support Windows 2000.

Please install DirectX 8.1 or later. You can download it from, or contact our support department. DirectX is also available on some Noldus installation CDs.
Also ensure that the hardware or software decoder you are using is capable of these playback speeds, as many of them do not (officially) support other playback speeds than 1x.
