[linux-dvb] Question about NAPI section filtering

[Steve Brown <sbrown@cortland.com>]

I have a feed where all the PMT's have the same PID. The PMT sections
seem concatenated until a ts block is filled and the remaining PMT
sections are in a following ts block.

The section filter reasonably only returns the first section in each ts
block.

How do I get access to the remaining PMT sections other than the first
in each block?

I have two commercial receivers that parse this correctly.

Attached are dumps of the PAT and PMT's.

Thanks again,

Steve
