I think you are right "TS continuity errors" it can explain why hardware
encoder is more sensetive than vdr-xine. VDR should be more stable if
there is a short stop in mpeg stream or channel keys. Sometimes when I use
vdr-xine and switch to DVB-T channel FTA or pay channels after 1/10 sek No
signal picture that comes whith vdr-xine show up for a short while and
then it continues. If I do the sam thing with FF it can freeze for a short
while instead of No signal picure and after about 10 sek.... crash or
change channel to 1.
Here is a NEW crash with osdteletext only. I removed the ttxsubs patch but
I had to patch with vdr-1.3.1-softcsa-0.0.8.diff also my family wanted to
watch tv but it does not touch remux.c. :-)
I do not understand why it crashes because the new channel (DVB-T) start
ok but after about 10 sek it crash or change to FTA channel one. As I said
before if I connect DVB-S card locally it works which is strange because
that data is not interesting any more except if I record a DVB-S channel.
If I record a DVB-S it works without problems.
Core was generated by `./vdr -D 0 -D 1 -P sc -P osdteletext'.
Program terminated with signal 6, Aborted.
