Hi,
I'd be really very thankful for any contribution on the following issue:
1. My motivation:
I do not like: KDE 4, kaffeine, xawtv and vdr for reasons I do not want
to discuss here.
I prefer to watch DVB-S TV with xine-ui and / or gmplayer.
2. The current state of development:
Xine-lib supports multiple audio PIDs demuxing TS streams since version
1.1.5.
Mplayer only supports one audio PID (usually the first one that it
finds).
3. My intention:
Switching audio PIDs of DVB-S streams on the fly with the appropriate
GUIs xine-ui and gmplayer.
4. My contribution:
A patch for the scan utility (part of the DVB utils) that features all
available audio PIDs
producing a _non-vdr_ output format.
This patch is not only necessary for revealing multiple audio tracks of
a DVB TV channel in case
you're producing a non-vdr channels.conf.
It also keeps up compatibility with mplayer which cannot (yet) handle
channel lists in vdr format.

5. Your contribution?
Who can give me hints about how and where patching xine-ui and gmplayer
appropriately so that multiple audio TS PIDS can be changed on the fly?
Who can offer appropriate patches?
Thanks
