You can just turn off updates in vdr setup menu. Then it shouldn't change anything and you can do it manually

My Cable provider or VDR seems to mess up the audio pid regularly for various channels. Is there a way (or patch) that I can keep the update pids on, except for the apids? They move the vpids around about once a month, so keeping vpid updating depending on sid is worthwhile, otherwise I would turn off the updatepids line.

I wonder if this could go in the atscepg patch?
Can you try if this also works if you insert the line
case 0x81: // AC3 DPIDs
after the line
//XXX case 8: // STREAMTYPE_13818_DSMCC
instead? I'm asking because I'd like to see whether there are also language descriptors available...
Klaus
Yes, language descriptors are present. However, ATSC also uses 0x81 as the AC3 descriptor tag. So we need another
case 0x81:
after
case SI::AC3DescriptorTag:
In case this is still current, can you please send me a (tested) patch?
Klaus
Sure, please see the attached patch.
