Hi,
"Comments on Revision AF:
1. ArtRdm table entry 17 incorrectly referenced the DMX start code. The RDM
data in this
packet excludes the Start Code."
Could this be the reason for the problem? any way could aplications have
implemented it with the start coded sent?

Commenteing out this code in packet-rdm.c
        //proto_tree_add_item(rdm_tree, hf_rdm_start_code, tvb,
        //        offset, 1, ENC_BIG_ENDIAN);
        //offset++;
The packet still show up as malformed as length and checksums seems to be
incorrect still. Should I go ahead and remove this code any way?
Could the rdm dissector be called with a DMX StartCode in any case?
Regards
Anders
