You are right, it would pick the last one. An easy fix.
A bigger concern to me is the overlap in functionality between the dvb
and hdtv code, including the kernel driver. I would think that a little
surgery on the pchdtv driver to use the same interface as the dvb driver
and include the kernel-level filtering and assembling of sections would
avoid maintaining both sets of myth code. Though, I doubt I have the
skills to do much about it.

At the time I fish the pmt pid out of the pat, I haven't yet received
the pmt. I have to wait for it to identify the video/audio streams in
I will let the patch age a little and see if there are more comments.
