Are you referring to

  ANIXE HD;BetaDigital:10832:hC23M5O35S1:S19.2E:22000:767=27:0;771=deu:0:1:61202:1:1057:0

Please try


That should fix it - this channel doesn't have a separate PCR pid.

The above patch fixes the replay problem with VLC. Thank you.

I am sorry for the late reply.
I had only tested replaying a recording from AnixeHD with the above 
patch applied.
I went through my channels list today, searching for a channel where 
PPID!=VPID, but could not find one at first glance.
