That's the behaviour I'd prefer anyway, my TV has a better range of
options for dealing with 4:3 than VDR etc. It would be nice if it could
switch automatiaclly, but I don't think the necessary signal pins are
there in S-Video, unless that's what some of the extra ones besides the
usual 4 are for.

That's something to do with NPTL replacing an older threading mechanism
and the linker having to work around it? I've tried reading
<http://people.redhat.com/drepper/assumekernel.html> but the author
seemed to get so involved in the background detail that he completely
forgot to explain LD_ASSUME_KERNEL which was supposed to be the point of
the article!

Yes, I found that eventually, and the Jump feature you can get with the
red button, so I got to the 10 minutes out of the 2 hour show I wanted
in the end!
