output. For example, after the device is configured for recording
or monitoring live video, it cannot be used concurrently for
accelerated video playback or vice versa.
o If the device is not available for hardware accelerated playback,
the subsystem will perform software playback automatically.
o In order to achieve accelerated video playback, open the Digital
Video object.
o When TV output is enabled, the device cannot be used for recording
or monitoring live video or hardware accelerated playback. In
order to use the Enhanced Video Device Driver, you must disable TV
output. To do so, use the ThinkPad Features object and select
Video-in to disable TV output.
o During video recording, the live monitor window might flicker.
o The live video in the monitor window might be distorted if the
monitor window is other than half size, normal size, or double
size.

o When the monitor window is in focus, you can press Shift+F6 to toggle
between full-screen video or the previous size.
