Hi Levente > Thank you Martin, this is a nice description!

The only thing that I find it makes it crash is when it uses an accelerated video driver. Try using it with the plain old X11 driver: gopchop -v x11 <filename> and you may find it's a bit more reliable... > additionally, dvbcut has individual frame precision.

All I can say is that from my brief dive into the subject the whole topic of PTS is a bit of a black art: far more complex than I was expecting (and I'm a pretty experienced professional engineer). I'm just amazed that tools like dvdauthor work at all. IMO it's not anything to do with the NTP daemon though.
