<p>Hello everybody, <br>
</p>
<p>let's see, I am still having problems with Unicable/SCR on my
mythbox.</p>
<p>I don't find anything almost on the internet regarding mythtv and
unicable, nothing very recent, is anybody using this?<br>
</p>
<p>My problem is that even if I have several receiver cards, I can
only tune in to one channel. <br>
</p>
<p>I have tried my own suggestion from below and created a second
videosource... the same, if I record one channel, I also can watch
only this channel even though I have more than one receiver card.
<br>
</p>
<p>In my original mail I forgot to mention: I am on myth version
0.31, on ubuntu focal. <br>
</p>
<p>Is Karl Egly here? I saw that the original unicable patches came
from him, I wonder if this part of the code is alive...</p>
<p>Thanks for all suggestions in advance, <br>
</p>
<p><br>
</p>

Hi everybody,<br>
<br>
after years using my mythbox with great success and relatively
little suffering, I had to move my server to a location a bit
further away from the sat dish and there is only one cable
available so I decided to switch to unicable and this is quite a
headache... I think I have several problems, I am not even sure
where to start. Maybe I first describe what I have:<br>
<br>
I have a Selfsat H50DCSS antenna - a flat satellite antenna with
incorporated 2x legacy and 1x unicable connections.<br>
<br>
I have the unicable connection fed through the window and there
connected to the inhose coax cable that originally was laid for
cable tv. At the location of the receiver at the other end of that
cable, I have a 1-to-4 splitter (alternatively 1-to-2), connected
to my SAT inputs - a digital devices cine S2 V6.5 card plus one
DuoFlex S2 extension card (which does not seem to work, I keep
that pending for later).<br>
<br>
I am also running four loopback devices (link 0:4, 1:5, 2:6, 3:7,
this is working) .<br>
<br>
Then I have four input cards defined, one for each loopback
device, from adapter 4 to 7.<br>
<br>
Card 1: /dev/dvb/adapter4/frontent0; type DVB-S, delivery system
dvb-s2, DiSEqC Unicable (Userband 0, 1210MHz, Pin -1, repetitions
I tried 1, or 9, or 15, works all the same), type LNB
(Universal-LNB (Europe))<br>
<br>
Card 2: same for adapter 5, except Userband 1, 1420.<br>
<br>
Card 3: same for adapter 6, except Userband 2, 1680,<br>
<br>
Card 4: same for adapter 7, except Userband 3, 2040.<br>
<br>
<br>
Video Source, one defined. Name "Unicable". Only EIT, frequencies
europe-west, etc. etc.<br>
<br>
<br>
Input connections: Card 1 and 2 connected to unicable, card 3 and
4 for now to "nothing", for later trouble shooting (these to cards
error out, the other two cards show as available in the frontend).<br>
<br>
Input connections are configured fast tuning "never".<br>
<br>
I think that is a relatively complete description of the setup.<br>
<br>
<br>
Scanning for channels was quite difficult - I could never do a
complete scan (tuned), so I switched to a legacy input on the
antenna, then I scanned, and once I had the transponders, I could
switch back to unicable and do a full scan of all known
transponders. I would get about 600 channels less and many
transponders which would have signal on the legacy output of the
antenna do not have signal on the Unicable output, but nothing
important seems to be missing, so that is OK for now. I also have
optimized the antenna orientation with a sat finder, I think that
made it much better. With the 4x Splitter while scanning, I get
about 64% Signal and S/N of about 25%, if that means anything.
Reception seems to be stable for now.<br>
<br>
Several things seem to not work very well, but right now only one
problem is consistant and (finally, thanks for reading up to here)
I dare to ask for help:<br>
<br>
It seems I can only watch or record one channel even though I have
two working cards. Once a program is recording, I can still enter
live tv, I see the same channel as is recording, I can switch
between the two sources (Called SAT#1 and SAT#2), but I cannot
change channel, neither on the card busy with the recording (I
have configured the input to allow for 2 concurrent recordings, so
I should be able to switch to another channel on the multiplex).
nor can I change the channel on the second card, it will also only
tune to the channel that is currently recorded on the other card.<br>
<br>
One solution that occurs to me is to create another video source
for the second card - I have not tried, I do not know whether that
would work but that was not necessary in the past, one video
source would work for several tuner cards. So I hope to get a
better suggestion from you.<br>
<br>
Thanks a lot in advance!<br>
