This issue turns out to have been a false alarm. I sent in my questions
about it after having spent a good part of a couple days testing the
equipment. Late last night in some final testing, I adjusted some
additional settings and now both tuners seem to be working fine. There are
a few strange things when watching live TV--e.g., when changing channels
the tuner sometimes goes back to a channel that had been previously tuned.
But test recordings I've tried so far have worked fine. Since I watch very
little live TV, I don't expect the intermittent strange issue mentioned to
be much of a factor. So, sorry to have bothered the list which what seems
actually to have been a user issue (ignorance).

Hi. This list seems to be somewhat dead, but when I try searching on my
issue, results from this list always come up. So it seems worth a try to ask
for some help here.
I got a couple of these tuners used for a pretty good price and am currently
trying to test them. I'm want to determine at this stage whether they are
functional so that, if not, I can send them back to the seller for a refund.
The target system is a new Gentoo install on the Liva X, which is also
running MythTV. So I've hooked up the tuners, loaded the firmware (firmware
gotten via Gentoo) and modules, gotten them recognized in mythtv-setup--and
even written udev rules--and am trying to proceed further.
I tried a channel scan under mythtv-setup, which gives some odd results; I'm
not any kind of myth-guru, so maybe the results are only odd to me. The scan
does finish and seems to find channels or to update channels, but it finishes
with the message "no new channels found."
When I attempt to watch live TV through the MythTV interface, though, the
only channels I can seem to tune are 5 and 6: trying others results in either
a blank black screen or an error message (something like "failed jump"). So
something is not working right here. Perhaps I should mention that I'm using
the up/down arrows on an attached keyboard to select channels (no remote). In
any case, those may be MythTV issues, or MythTV user issues, which cannot be
addressed here.
But what perhaps can be addressed are errors I'm seeing in dmesg output. Both
tuners output the error message seen in the subject heading of this e-mail as
I try to tune stations.
I'll append below some dmesg output that may provide further insight into the
issues I'm confronting:
