Trouble with high speed transponders. SR28000-30000(Solved)

[Kompik]

I have 6991, on transponder with symbol rate less than 28000 everything OK.
But if i tune to transponders with symbol rate more than 28000 i have a lot of error.

I use last drivers 121021 on my debian 2.6.32-5-686

I tune to Intelsat 15 85°:
11960H, 28800, DVB-S2, PSK8

At slower transponders everything OK. transport_error_indicator on pid 3570 (

please, try this test driver:

http://www.basicupload.com/t9br0ve05cgm

and report back your results. if it doesn't help it could be your motherboard can't handle such data-rate and the solution then would be to optimize transfer buffers in the driver to compensate for your motherboard performance issues.

I found the cause of the problem!

I have one system with six of TBS6991.
Cable from Satellite dish connected to 4way splitter.
Second card (/dvb/adapter3) tune to Intelsat 15 85° 12080 H 26700 3/5 8PSK
Fourth card (/dvb/adapter7) tune to Intelsat 15 85° 11960 H 28800 3/5 8PSK
Both card connected to LNB via 4way splitter.

Problem was solved by taking away option "-v 18" in command string in dvblast of card7.

Old and test drivers work fine.

Sorry for the trouble
