Thanks for your advice!
I've tried to follow it but still get the libfaad errors[1] and no audio
with plain xine on the previously mentioned sample. No audio on the
relevant channels with vdr+xineliboutput+sxfe either.
Can you actually play the audio of that http://www.nilux.com/2.ts sample
with plain xine?

Perhaps you would be as kind as to explain a bit more about your
compilation to make completely sure I understand exactly what you mean?
A private mail is fine if it is irrelevant to the list.

I've tried building both with the yavdr source package and with a plain
xine checkout but with the same result. Configure says it uses internal
libfaad and ldd no longer says that the xine faad plugin file is
dynamically linked to libfaad. I had to make some changes to get it
compiled, though, as shown in my step by step description below[2].

Do you apply any additional faad or xine patches?

Thanks in advance!

Cheers, Jonas

[2] Building from a xine-lib-1.2-vdpau checkout (the copying around to
tmp is slightly silly but it follows the structure I needed for the
yavdr package):
