I have it normally connected to Comcast cable which should pipe

automatically so that the audio stops working. If I manually change
VDR
to not auto update and put the APID in then it squeeks rather than

does the same this with OTA channels too - although I can only get 4

ATSC uses only AC-3 audio, so the Apid should be 0 and the Dpid
needs to
be set appropriately. Since the sound squeaks, whatever value you have
set for the Apid should be the Dpid.
For example,
WIFR-Wx:495000:M256:C:0:1984:0;Dpid:0:0:2:0:0:0
Perfect... Thanks
Is there a way to keep auto update on, but stop Comcast from sending
wrong pids? It keeps settings all audio options to 0 and some vpids
too?
The streamtype for those AC3 PIDs is 0x81. Adding this to pat.c will
add the digital PIDs correctly.

Perfect. 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:
