Are you shure this is related ?
Crashes in qt is frontend specific (i.e. the GUI) and should not happen
in the backend ? I'm not sure this is the same issue. I'm away from my
machine at the moment (am in las vegas at the mo) so can't check the
code to verify, but this looks like a error in the signal monitor code
as oposed to the previous eit scanner.
Did you do a full restart of the front/back end ?
Cheers

Crashed again!
In pespacket.cpp i changed the return to false:
{
VERBOSE(VB_RECORD, "AddTSPacket: Out of sync!!! "
"Need to wait for next payloadStart" +
QString(" PID: 0x%1, continuity counter: %2 (expected
%3).")
.arg(packet->PID(),0,16).arg(cc).arg(ccExp));
return false;
}
After 10 hours i got this now:

multiplex of
channel 29
***************************************
It's not the same channel as before, this channel also was set to
useonairguide=1. Did i mess up the database when i used some sql
commends and
set useonairguide=0 for channels i don't use? How does the crawler use this
attribute? Is it ok to activate only some channels on a transponder?
Or could my hardware be damaged, i have some problems with 2 transponders
whose channels have interferences!?
Thanks,
Flo
