After some off-list pointers by Devin, I tracked this down to user 
error.  I thought I was compiling tip for xc5000-improvements-beta but 
was not.  This is now working and composite input video works well on my 
950Q.  I notice no difference from previous version (wouldn't really 
expect to based on changes).

Thanks,

John

Re: CX24123 no FE_HAS_LOCK/tuning failed.

[John Donoghue]

Rex,

The Hauppauge WinTV Nova-S-Plus has had problems with hi-band
transponders since the 2.6.20 kernel or thereabouts.  The Optus D1
transponders all seem to be hi-band.  See the thread at:
http://bugzilla.kernel.org/show_bug.cgi?id=9476 where I outlined a
fix which works OK for this card, but is not robust enough for
general use.

In my last post to that thread I make a reference to the isl6421.h
file, but it should be to the isl6421.c file.  I was confused as that
file identifies itself as isl6421.h in line 2.  I made no change to
isl6421.h.

Regards,
John

Glad to hear it's working for you.  If you're using composite, then
you will not see the benefits of the tuning performance, but you
*will* see the power management benefits.  This means the tuner chip
won't be enabled when you're not watching TV, which will result in not
causing as much drain on your battery (if you have a laptop) and the
device will be much cooler.

I am still looking for strategies in the code so that the tuner is not
enabled when capturing on composite or s-video (which will reduce
power consumption further), but the code changes are non-trivial.

CX24123 no FE_HAS_LOCK/tuning failed

[Andrew Stevens]

Hi John, Rex,

As an extra data-point: John's patch worked fine for me (Quad LNB with 
integrated switch for Astra-28.2E).  I'd really like to build on John's patch
to work up a full fix.

To do this I'm trying to track down a cx24123 datasheet.  I don't suppose 
either of you guys has a pdf?

cheers,

	Andrew

Re: CX24123 no FE_HAS_LOCK/tuning failed.

[John Donoghue]

My apologies to Rex and to those contributing to the XC5000 thread for
having caused the two threads to become mixed - very sorry!

Rex, this message should effectively start a new thread, so that
hopefully your problem becomes more visible to those who may be able to
help further.  For my part, I am at a loss on how to proceed.  3 people
have e-mailed me in the last 6 months to indicate that my "patch" fixed
their problems.  However, one guy could not get his setup working, but
I'm not convinced it was the card which was at fault.  The various debug
outputs you have posted are very similar to mine, except for the
parameter differences between Optus D1 and Astra 2.  At least they are
indicating that the 22kHz tone is now being generated.  I don't think
the numbers for signal strength, S/N ratio and ber have any meaning,
except when the tuner is locked.

Have you any way of monitoring the input/output of the Nova S Plus?  I
use a cheap "Satellite Finder" which I leave permanently in-line in the
coax.  It indicates the presence of the 22kHz tone and the 13V/18V
signals, as well as an uncalibrated signal strength.  Also, feel free to
dismiss this and it is a long-shot, but are you absolutely sure that you
are pointing at Optus D1 and not C1?  They are fairly close.  It should
be very easy to check by trying to szap 12407 V, srate 30000, fec 2/3,
which is on Optus C1 and which seems to be beamed at New Zealand.

Best of luck,
John

CX24123 no FE_HAS_LOCK/tuning failed.

[Spammers please]

Hi All,

I've been struggling setting up my new HTPC.

I've got 2 cards, Hauppauge WinTV Nova-S-Plus in a machine with lots of 
grunt and memory,
a brand new LNB (old one was broken), freshly aligned dish (properly 
with a meter and all)
to the Optus D1 satellite.

I initially installed mythbuntu, and have upgraded it, it's now running 
kernel 2.6.27-11-generic.

I've downloaded/installed the latest v4l-dvb drivers, all to no avail.  
I can't get a frontend signal lock.

I've switched on some debugging and tried a few tweaks...
