Did you have "AIS Targets Only" set to "ON" in the TCP/IP NMEA Client setup? If so then COG and SOG would be coming from the iPad versus from the laptop. I would recommend you make sure it is "OFF" so all NMEA data is used.
Another thing to realize is MacENC is running non stop, but each time iNavX is started you need to give it some time to receive all the AIS target info..

It may be that iNavX had not yet received the targets position, course or speed which is needed to compute CPA and TCPA.
With iOS 4.2 (November release) this will be less of an issue because apps won't be exited, but only suspended.
