Its now happened spontaneously, without unplugging anything. It may be that the dvb-usb module de-initiallised itself. I have left tzap running for about 3 or 4 hours on in two separate sessions with the two tuners, tuned to different channels. One of the channels seems to maintain lock perfectly, the other one seems to come in and out (the led on the front of the stick is flashing green about every half a second rather than the steady green of the other one). Anyway sometime later I noticed it has stopped, and that some form of oops was on the console. Syslog had the following it it. Something (repeated bulk message fails? - just before the 10 shown here, there where 150 above, before being interrupted by another task logging something) seems to have caused dvb-usb to de-initialise itself, which threw it into the same sort of failure sequence as before.
