Each profile is associated with a set of minimum features a device must support
in order to achieve certification.
The following table lists profile-specific features.
Devices can exceed these minimum requirements but you should never rely
upon this when performing profile encoding.
By selecting the correct profile of the target DivX Certified device from the
Select
Profile Wizard prior to encoding you ensure the video stream will always play
correctly on the device.
