A display name uniquely identifies the filter. Display names have the following format:
@device:sw:GUID\GUID
For example, the display name for the LEAD MPEG2 Transport Demultiplexer is: @device:sw:{083863F1-70DE-11D0-BD40-00A0C911CE86}\{E2B7DF1A-38C5-11D5-91F6-00104BDB8FF9}
A list of display names for common filters can be found in Constants.PreferredFilters.
Please see SetPreferredFilter for more information on filter display names.
