[linux-dvb] Technisat Skystar HD2 success

[Tim Hewett]

The Technisat Skystar HD2 card (Azurewave AD SP400 clone) has now been  
used successfully with the current mantis tree.

It is necessary to use szap to set DVB-S2 mode first, even if the  
transponder you want is DVB-S (discovered by chance). If this isn't  
done then it does not lock on to the frequency.

So you do the following:

szap -r -p -l UNIVERSAL -t 2 -a <card> <channel>

CTRL-C that after it has settled, then:

szap -r -p -l UNIVERSAL -t 0 -a <card> <channel>

Then (leaving the above line running) you can do:

cat /dev/dvb/adaptor<n>/dvr0 > file.mpg

and it then records error-free video.

As mentioned previously you need to change linux/drivers/media/dvb/ 
mantis/mantis_vp1041.h before building the drivers. Change the line:

#define MANTIS_VP_1041_DVB_S2   0x0031

to

#define MANTIS_VP_1041_DVB_S2   0x0001

This will let the driver detect the card properly on bootup due to its  
different subsystem IDs, otherwise the frontend isn't registered.

HTH,

Tim.
