Hmm...

The latter, I'd say. I had some... interesting problems with the Debian
runvdr script, so I rewrote it in C; you may find it to be of some use. It's
somewhere in
<URL:http://zap.tartarus.org/~ds/debian/dists/unstable/main/source/misc/vdr_1.3.11-2.ds.diff.gz>

Also in that file, there's a patch for vdr which causes it to exit on SIGUSR1
unless it's recording. (The shutdown-delay thread suggests that other checks
are needed; patches welcome...)
