DataSource support single SourceStream.  SourceStream however can contain 
multiple media streams which is supported.  handling of multiple streams 
from within a single file is not functionality specifically support by 
DataSource implementation by rather by standard helix file-format modules:

DataSource  -----------> Proxy F. Sys ---------> RealMedia File Format 
(chosen by mime-type) === Demuxed A/V streams ====>
