Ah, I see Dale has been helping you out. He was a very patient

In a generic sense, yes all HVR-1600's from 74000-74999 are.

It's could be a reason why analog TV may not work. Composite or SVideo
should certainly be OK. Have you tried those?

The tveeprom module can decode the EEPROM on the HVR-1600 and knows it
has a "TCL MNM05-4" analog tuner assembly. But looking at the entry in
the table in tveeprom.c:
/* 100-109 */
{ TUNER_PHILIPS_FMD1216ME_MK3, "Philips FMD1216ME"},
{ TUNER_TEA5767, "Philips TEA5768HL FM Radio"},
{ TUNER_ABSENT, "Panasonic ENV57H12D5"},
{ TUNER_PHILIPS_FM1236_MK3, "TCL MFNM05-4"},
---> { TUNER_ABSENT, "TCL MNM05-4"},
{ TUNER_PHILIPS_FM1216ME_MK3, "TCL MPE05-2"},
{ TUNER_ABSENT, "TCL MQNM05-4"},
The tveeprom parsing doesn't set any tuner type for that specific analog
tuner assembly (type 4 is TUNER_ABSENT).
I can't find the TCL MNM05-4 on the TCL King High Frequency website, but
I suspect the TCL MNM05-4 is similar to the TCL MFNM05-4 except without
FM radio:

They don't. By "tuner" the error message meant the analog tuner
assembly on the HVR-1600. The cx18 driver gripes when tveeprom doesn't
tells us what the analog tuner type is.

Yet, the cx18 driver searching for an analog tuner on the I2C bus yields
an RF oscillator/mixer chip and IF demodulator chip that are inside the
analog tuner assembly. The I2C addresses and the presence of a TDA988x
chip makes me further suspect it is like a TCL MFNM05-4, just without FM
radio.
I'm just not sure the analog tuner driver will let you tune to a channel
when you have a tuner type of TUNER_ABSENT set.
Can you unload the cx18 module and reload it with a
# modprobe cx18 tuner=43 radio=0
That'll tell the cx18 driver that, for the first card, the analog tuner
is a TCL MFNM05-4 but that there is no FM radio.
That's just a guess. You can guess other tuner types and try to see
what's best. The list of numbers is in linux/include/media/tuner.h. I
suggest you try only NTSC tuners. ;)
The tuner type parameters are in
linux/drivers/media/common/tuners/tuner-types.c
in case you can find actual data on the TCL MNM05-4 and want to find a
similar existing entry.
When/if you find a good match for the analog tuner, then let me know,
and I'll get tveeprom.c updated.
