Maybe the cut function of VDR can be improved to move cutmarks relatively
to the start of a recording. If you get cutlists, the offsets BETWEEN the
cutmarks are the SAME, but the offset to the START of the recording can
DIFFER. A solution would be to import cutmarks into VDR and move the first
mark to the correct position with e.g. the left/right keys. The correction
offset can then be applied to all other cut marks automatically.

Not really. Sharemarks uses the PTS in the TS-stream to place exact cut
marks.
The database server is still online, but the 3 year old last version of
Sharemarks
it not compatible with VDR 1.7. Maybe someone can revive the Sharemarks
script
and adjust it to new VDR versions.

But it still would be great to have the start timestamp (and maybe the
option to
move all cutmarks with the same offset) to import non-VDR cutlists.

Better NOT. NOAD worked relatively well, but markad messes up cutmarks.
There are
channels with over 50 cutmarks in one recording. I really don't want to
remind how much
time it has cost to remove so much wrong cutmarks from ONE 90-minute
recording.

Or VDR just uses cutmarks with NTP-based timestamp and PTS in the marks
file ;-)
That way the PTS can be used and timestamps if there is no PTS or broken
PTS.

Best regards,
