These 2 patches make RDT support pretty complete now:

From Martin Mathieson:

packet-rdt.c:
- register a configurable UDP port (off by default, but needed where setup traffic isn't captured)
- dissect extra 'buffer info' fields
- move bit fields into 'flags' subtrees
- misc. minor fixes and improvements (mainly formatting)

packet-rtsp.c:
- improve detection of RDT as the transport
- allow interleaved frame data to be dissected as RDT packets
