Hello,
== Antti:
May I ask, if you have the same one stick?
Does it work without problems ?
I don't have just similar stick, but I tested 1-2 sticks having that
same chipset. No problems at all.
== everybody:
I have final tested it under W-XP SP2 with orig drivers and SW.
It goes into problems after some time too, BUT there is a difference: It
is able to "recover" from it itself and it plays again (for some time).
As I wrote - it happens quicker and more frequently on TV channels with
lower/worse signal. That is why I thing that tuner will lose "tuned"
status to exact freq.
Would be not possible to solve this (to re-tune) in driver ? It seems,
that in W-XP is something like that in drivers.
I am pretty sure problem is RF-tuner. It warms and goes off from
frequency a little, which causes signal level drop. As signal goes
weaken, from a point of demodulator, it starts getting decoding errors.
Retune fixes things for a while as tuner is calibrated each time when
tuning is done. If you wait a little longer, demod will lose signal LOCK
and retune is issued - as what happens on windows driver too.
It is possible to add some early re-tune logic to demod driver, but it
does not sound very wise for single problematic device. Also better
approach could be to issue tuner calibration on 5 minute intervals or
so. I am not sure if calibrating tuner is possible at runtime, but it
should be easy to test.
Thats the Problem - I do not know, how to do it without breaking
recording. Can You give me a Tip ?
Which command to "recalibrate" ? Tzap breaks it.
Check the function:
it9137_set_params and it913x_init. You have to do a little bit testing
here. Like set a timer which calls those routines once in 5 min or so.

Anyhow, I am not going to waste any time for workaround this strange
issue. You are simply only one having it :) Just get new similar stick
and hope it works better.
Of course, I understand. Thanks anyway.

Hello,
I have test FW version 12.10.04.1
(FYI dmesg changes follows)
The problem without change.
I did want to test the DVB-T stick under Windows XP, but in VirtualBox
works the tuner not at all - I get just jerky sound, no video.
But there is older driver (12.7.6.11) - but don't thing the problem is
there - rather in VBOX.
And no free partition to test.
OK, thank for the testing anyway.
I have few different it9135 devices. Could you find some picture of
yours, I would like to test myself if I had same device.
