Remarks

Gets or sets the preferred MPEG2 splitter display name. A display name uniquely identifies the splitter (or any filter). Display names for software splitters have the following format: @device:sw:GUID\\GUID. For example, Microsoft's 'MPEG-2 Splitter' display name is: @device:sw:{083863F1-70DE-11D0-BD40-00A0C911CE86}\\{3AE86B20-7BE8-11D1-ABE6-00A0C905F375}
