Last drivers scan took 1046198 ms / 18min

1) Can you reduce scan times in drivers(old 3 min/last 18min)?
Or is it not possible?
Or is it just a problem with my old hardware(MediaTV Digital Home III)?

2)If you use the format /opt/bin/mediaclient --blindscan 10 , new found transponders are visible on the screen.
Example:
show data output
waiting for 1 secondspause N sec
OK 474000 0 FEC_AUTO QPSK INVERSION_OFFpause N sec
OK 490000 0 FEC_AUTO QPSK INVERSION_OFF
If you use the format /opt/bin/mediaclient --blindscan /dev/dvb/adapter0/frontend10 , new found transponders are not visible on the screen.
show only first data output
Succeeded this device supports Hardware Blindscannext  data output not visible all data comes at the end and immediately starts scanning channels
In telnet everything is as it should be, line by line, but in enigma there is a problem, there is only one line at the end of the scan.
It seems that some special character is missing at the end of each line that is in the line 'Succeeded this device supports Hardware Blindscan'.
It's easy to check:

replace
if self.terrestrial_tunerName.startswith("Sundtek"):
- cmd = "/opt/bin/mediaclient --blindscan /dev/dvb/adapter0/frontend%d" % nim_idx
+ cmd = "/opt/bin/mediaclient --blindscan %d" % nim_idx
print "SCAN CMD : ",cmd
self.terrestrial_search_container.execute(cmd)
Use Sundtek DVB-T/T2
