New blind scan for DVB-C/T

[Sundtek]

PLP is set to PLP Auto

the Blindscan transparently finds DVB-T and T2 channels.

Try again using the latest driver, it has a stronger blindscan for some other DVB-T2 variations.

Try again using the latest driver, it has a stronger blindscan for some other DVB-T2 variations.

I check out the new driver.
They have a very big problem.
Example:
490mhz frequency Latvija
old driver -->snr 5%-13%
new driver  -->snr 0% and "Tune failed!"
hence blindscan for dvb-t not works...

[Sundtek]

Please contact us via Skype (sundtek) to verify that on your side.

Could it be that you are blindscanning DVB-C?

/opt/bin/mediaclient -D DVBT -d /dev/dvb/adapter1/frontend0
/opt/bin/mediaclient --blindscan 4

ok figured it out the delay needed to be increased for DVB-T/T2 scanning.
DVB-T only scanning is very fast.

DVB-S/S2 Blindscan is now also included
