When an RTP stream is present in a trace some packets are incorrectly decoded
as DPLAY instead of RTP. You can use the "Decode As" option as a temporary fix.
If you disable DPLAY in the "Enabled Protocols", it correctly decodes as RTP.

These RTP packets correctly decode in version 0.99.8, but decode as DPLAY in
V1.0.0.

This seems to affect RTP ports in the 6xxx range and the 2xxxx range (see
attached trace).
