System streams are defined in the original MPEG standard. MPEG-2
introduced transport streams and program streams. Transport
streams are really different and are intended for broadcast
streaming, which is why they're used in DVB. GStreamer doesn't
currently have a transport stream demuxer.

Uh, they _only_ handle element streams.
