We just had an identical problem on the ivtv lists with an HVR-1600 and
a TCL MNM05-04 tuner with the cx18 driver.

tveeprom.c can identify it, but tveeprom.c doesn't know what parameters
to tell the ivtv driver.  It returns TUNER_ABSENT instead.

This is the problem.

Yes.  If 81 is the the FQ1216LME MK3, then this will likely work.  Let
me know how the reception is, and I can get the entry changed in
tveeprom.c.

Yes.  I just fixed this bug in the cx18 driver a week or so ago.
