SkyStar s2 - cant play DVB-S2 channels

Tomasz Bąk

Hi all

I have problem with watching all channels (SD and HD) on dvb-s2 transporders.

I have no problems with dvb-s transporders, even HD channels.

I also have no problem with scanning dvb-s2 transporders.

Im not sure if it is hardware, drivers or software problem.

Here is some logs:

Thx for answers :)

Might be caused by the card having issues with high bandwidth transponders? See "this"

Tomasz Bąk

Yes, I read about this issue, but under windows those chennels play very well.
Anyway, I tried investigate this high bandwidth problem, but I can not find information about which transporders are high or low bandwidth.

Tomasz Bąk

Now I can confirm that it was a hardware problem. After replacing the oscillator from 45 to 80 Mhz no more problems with "Continuity counter error" even on high bandwidth HD channels.

I'm not sure about the safety of this solution. Will see if this card will burn :)

Cheers.
