Hi,
after upgrading to from to VDR 1.6.0 I have noticed that the DVB-subtitles stay on screen for about one second too long. The difference is noticeable compared to 1.4.7 with subtitles-plugin. Problem exists on both live-viewing and record-viewing. I use Fujitsu-Siemens DVB-C FF-card as output.
In addition I compared recordings of a same program from Finnish Yle TV1 and TV1+ (TV1 has DVB-subtitles, TV1+ is same channel with subtitles "burned in" to video), and subtitles stayed on the dvb-subtitled recording about one second longer compared to the "burned in" video version. Subtitles start time seemed to be same on both versions. I can provide both recordings for testing if needed.

I uploaded samples (90MB) to rapidshare: http://rapidshare.com/files/110035063/dvbsubtest.tar.bz2.html
In the file are 2 two minute recordings, from TV1 with dvb-subtitles and TV1+ with burned in subtitles. There are good examples of the problem at 0:15 and 0:30.

The timeouts are given in "seconds", and can be seen when the line
static bool DebugConverter = false;
is set to "true" in dvbsubtitle.c. From what I can see in your example, the timing appears right to me (although I haven't used a stopwatch, just counted "twentyone", "twentytwo", etc).
Maybe you can do some more precise measurements, but as it stands now I have the feeling that the "burned in" subtitles are shown too shortly.
