You are mixing Cyfra+ channels with Platforma N channels. One and the same channel (for example, TVN HD) is opened with Cyfra+ subscription, but has longer time response and freezes.
Example from slabypl log:
Oct 04 21:30:11 192.168.2.101 [mg0] <- CW from newcamd XX.XXX.XXX.XXX:XXX14 (2804ms)
Oct 04 21:30:11 192.168.2.101 [mg0] 2804 msec -- Fri Oct 4 21:30:08 2013
Oct 04 21:30:11 192.168.2.101 ===== Seca ECM on CaID 0x0100, pid 0x0529 ======
Oct 04 21:30:11 192.168.2.101 prov: 000068
Oct 04 21:30:11 192.168.2.101 cw0:0 84 EB 5F CE 0E 3E 0F 5B
Oct 04 21:30:11 192.168.2.101 cw1:0 3F 18 C9 20 C7 27 76 64
Seca (prov: 000068) is CYFRA+ encryption
The same channel is opened with Platforma N subscription without any problem and freezes:
Oct 05 13:27:46 192.168.1.34 [mg0] <- CW from newcamd serv3:XXX26 (315ms)
Oct 05 13:27:46 192.168.1.34 [mg0] 315 msec -- Sat Oct 5 13:27:37 2013
Oct 05 13:27:47 192.168.1.34 ===== Conax ECM on CaID 0x0B01, pid 0x0461 ======
Oct 05 13:27:47 192.168.1.34 prov: 000000
Oct 05 13:27:47 192.168.1.34 cw0:0 CF 79 BD 05 69 6F 20 F8
Oct 05 13:27:47 192.168.1.34 cw1:0 43 53 72 08 BA 39 87 7A
Conax (prov:000000) is Platforma N encryption.
Do you see the difference in time response: 2804ms in the first case and 315ms in my case?
If you have Cyfra+ subscription, it does not mean that Platforma N channels will open without any problem. yes, I know that many Polish channels have many encriptions. But it does not mean that you bought Polsat and can watch Cyfra+ or Platforma N together with it.
Make conclusion...
P.S. Pay attention to the server in your settings.
According to the log above,
Oct 04 21:30:11 192.168.2.101 [mg0] <- CW from newcamd XX.XXX.XXX.XXX:XXX14 (2804ms)
server is added in numerical form. Why?
MgCamd is clever enough to understand server name (it is encoding it automatically).
Use the following form:
Oct 04 21:30:11 192.168.2.101 [mg0] <- CW from newcamd serverX.cc (complete name as it is given in the billing):XXX14 (2804ms)
