This mornig I found strange behaviour: VDR claimed to show & record Channel 4, but program was from Ch 1. And recording from yesterday was also similar way.
I tested bit more, and found out that if I first tune to Ch 3, which is on same transponder as 4, I can get Ch4 working. But if I have tuned to Ch1 or Ch2, after it change to Ch4 shows picture of Ch1, but claims to be on Ch4.
Ch1: YLE TV1;YLE:578000:I0C12D0M64B8T8G16Y0:T:27500:512+128:650=fin:2321:0:17:8438:4097:0
Ch4: Nelonen;Ruutunelonen Oy:490000:I0C12D0M64B8T8G16Y1:T:27500:512:650=fin:576:0:65:8438:8193:0
Channels have same pids, and apparently vdr commands tuning to another transponder, but it's not done, and vdr gets legal pid values from wrong transponder.
My setups is: Technisat Airstar2 Nova-T TEchnotrend DVB-S 1.3 as output.
My DVB-T signals is weak, but looks clean with Airstart (No bit errors). Tuning from 4 to 1 works perfectly, no confusion there.
Apparently I could avoid problem saying '1+2 with card 1, 3+4 (possibly all other channels on same transponder) with card 0' or something similar. Is there some way to do it?
