See the reply I just sent to Stuart's message. The version check
is not designed to check for transport changes. The users of the
class, in this case tv_rec and dvbsignalmonitor, are responsible
for resetting the class on transport changes, and resetting the
known PAT version on a channel mismatch. It looks like it is
doing this, but a PAT mismatch only happens when the MPEG program
number doesn't match the expected value. But the program number
is by no means unique across transports. Hence you need address
ticket #1049 to address this properly, fixing it will allow
monitoring the transportid, networkid and serviceid...
