[linux-dvb] TeVii S470 in mythtv - diseqc problems

[O&M Ugarcina]

Hello Guys,

Just installed a S470 into my mythbox , fedora 12 kernel 
2.6.32.14-127.fc12.i686.PAE . Myth is .23 the most recent fedora package 
, the drivers for dvb card I have at the moment were pulled in 
2010-04-01 . I assume they are pretty current . The problem that I have 
is as follows :
Most of my viewing is done on a Satellite connected to diseqc port 2 , 
and myth tunes into that with no probs at all , but occasionally I try 
to watch a channel that is on a second satellite - port 1 and here 
things fail . Myth tries to tune into the channel - then times out with 
error , during this the dvb driver crashes , and when I try to retune 
again with myth there is no lock on either satellite  . So I need to 
restart pc , then everything comes back on port 2 and myth is able to 
tune again channels within that first satellite . Any one else 
experienced diseqc issues with this card and myth ?

Second question what is the tool of choice to use to scan dvbs2 
satellites ? I tried dvbscan but it only picked up dvbs transponders , 
on dvbs2 it failed to tune . I saw that there used to be this utillity 
scan-s2 , but looks like it was abandoned a couple of years ago and has 
not been maintained since . So how do you guys do a transponder scan for 
dvbs2 ?

Best Regards

Milorad

I had the same issue, I have a combination of Hauppauge and Tevii card. The problems arrise when the order of loading of the cards differ from the order of card installed in MythTV. I have added module options to get the modules to use the same /dev/dvb device on boot.

Hope this helps for you,

Hans

Hello Hans,

Much thanks for your advice . I have done that options setting  and it
helped with my other issues . I have just worked out this problem . It
was connected with the changing of the DVBS card that I used for years
with a new DVBS2 and Mythtv . I thought that it was the drivers issue
- but it is not . My apologies to the DVB developers ( sorry Igor for
doubting ) . The issue is that Mythtv when dealing with DVBS2 card
will need to access an additional parameter from the dtv_multiplex
table which is mod_sys . In my mod_sys column  there was only "1" ,
instead of a proper setting such as "DVB-S" . After updating the table
, mythtv was able to execute a tune properly .


Best Regards
