And another bug
dvb.conv with missing CA pids

227.19.3.102:1234/udp 1 930 80,92,130


Use this and the 938 and 939 pid disappear, -W is needed to get the CA to be added

with -Y -W
debug: end PAT

remove the 80,92,130 from the dvb.conf

Why would adding the CA pids cause the Audio/Video pids to be removed
