Our NDI source is Scan Converter from NDI Tools. When we try to record this in a mix the interface often freezes and we are unable to stop recording. We have to ctrl-alt-del and log off to exit the session. We don't have a problem recording a mix with SDI sources.
I wasn't aware that the IO module had that recording ability. That could be useful when we need to expand the system. Again though I don't really want the extra cost to add NDI recording when I think it is reasonable to expect the TC1 to do it.
Don't get confused - the NC1IO *cannot* record NDI sources
