AutoPlay will automatically choose between conserving memory and maximizing speed in order to achieve optimal performance. This is the recommended setting.
Each page's data will be cached in memory after it's initial display. If any of these pages are viewed again, loading time is reduced, however memory usage will increase on the end user's system throughout the application.
Do not cache page data in memory. Each page's data will be reloaded from disk or drive, minimizing memory usage on the end user's system.
Disable the AutoPlay Media Studio audio engine on Windows NT 4.0 operating systems at runtime. The audio engine controls sounds such as mouse effects and any background audio playback. Due to a limitation in Windows NT 4.0, only one thread of execution for audio can be used in a project. This limitation affects the audio playback for the video object and the Media Player Plugin Object in AutoPlay Media Studio. If the audio engine is enabled allowing mouse effects and background audio, video playback will contain no sound. If the audio engine is disabled, only the audio for the video objects will play.
If video (containing audio) is an integral part of your application and Windows NT 4.0 is one of the operating systems you will be supporting, we recommend selecting this option even though it means sacrificing your other audio features. This setting only affects the Windows NT 4.0 operating system.
