Delayed subs: record from sat, crop in Shrink, burn to dvd, play

[Mudd]

Hi,
I guess I'm a newbie
My problem is as follows:
I record a movie on my hard disk-equipped Viasat box.
I later play that movie, while at the same time recording it on a DVD-R disc in my DVD-recorder (via scart).
Take the DVD downstairs, to my computer.
Open the movie in DVD Shrink (lovely program!) and crop it (remove start and end sequences).
Save as Video_TS
Burn this with Nero 7.
Watch the video on my TV via my regular DVD player.
After approx. one hour I notice that the subtitle (Swedish) is lagging 5 to 10 seconds, increasing as the movie continues. Where in the chain could this happen?

Does the subtitles FPS match the video FPS ?

Are the subtitles in sync BEFORE you edit it with dvd shrink? ...hmm...so the dvd recorder are making "switchable" subtitles from the viasat box?

I'm not certain what you mean - I work with pure video_ts (vob and so on), how do I even find the subs in these files? I have done som reauthoring with avi-files and separate subs (going from 25 fps to 23.997? i think) but I don't have access to the subs in this case.

When you load the DVD in DVD Shrink can you see the subtitle stream listed?
