[mythtvnz] Problems with Sky2PC/Skystar 2 DVB-S

[Stuart Whelan]

Hi Nick,

Thanks for the reply, a couple of questions:

If it was a dish alignment problem or cabling problem, would I expect
to see it in dvbtune?

My dvbtune output currently is:

stuartw at ubuntu2:~$ dvbtune -c 0 -f 1183000 -s 22500 -D 0 -p h -m -tone 0
Using DVB card "ST STV0299 DVB-S"

When I am having 'the problem the output is:

stuartw at ubuntu2:~$ dvbtune -c 0 -f 1183000 -s 22500 -D 0 -p h -m -tone 0
\Using DVB card "ST STV0299 DVB-S"

And when I think I managed to catch it going 'bad':

Signal=52412, Verror=0, SNR=53502dB, BlockErrors=0, (S|L|C|V|SY|)
FE READ UNCORRECTED BLOCKS: : Function not implemented
Signal=52565, Verror=0, SNR=53523dB, BlockErrors=0, (S|L|C|V|SY|)
FE READ UNCORRECTED BLOCKS: : Function not implemented
Signal=45366, Verror=52992, SNR=29856dB, BlockErrors=0, (S|C|)
FE READ UNCORRECTED BLOCKS: : Function not implemented
Signal=46733, Verror=65352, SNR=30636dB, BlockErrors=0, (S|)
FE READ UNCORRECTED BLOCKS: : Function not implemented
Signal=45351, Verror=65520, SNR=30051dB, BlockErrors=0, (S|C|)
FE READ UNCORRECTED BLOCKS: : Function not implemented
Signal=38548, Verror=65520, SNR=28371dB, BlockErrors=0, (S|C|)

Is this consistent with a physical problem?

How about that 'FE READ UNCORRECTED BLOCKS: : Function not
implemented' error, should I be concerned about that?

Kind Regards,
Stuart
