Hi Brad,
My documents indicate that Register 0x5D and 0x5E are read-only, and
populated based on the eeprom programming.
On your device, what is the value of those registers prior to you changing them?
If you write to those registers, do they reflect the new values if you
read them back?

Return it and get an HVR-950q. This has been a known issue for more
than 5 years and nobody's gotten around to fixing it (largely because
of limitations inside the V4L2 framework).

Note: we also had to tweak the API to mxl111sf_ctrl_msg to pass
the pointer to the state struct rather than the device, since
we need it inside the function to access the buffers and the

I have been doing some application conformance for VLC, and I noticed
something interesting with regards to the G_TUNER call.
If you have a tuner which supports sleeping, making a G_TUNER call
essentially returns garbage.
