Hi Kostya,
and thank you for your reply.
I tried to upload the clips to your ftp server this morning but it wouldn't let me in: '530 password incorrect'

- For my better understanding:
why would I want to demux and then mux clips, when I can 'remux' them in one step, including cutting.
- The merging of clips REALLY WORKS !!! Only the clips length information is totally wrong once you cut them.
Example: when I cut a 29min-clip back to 27min, after cutting it shows me something like 15min length when played again...??
- There seems to be no place where you mention the merging option in your manuals, or did I oversee them?
Can you please give me a new password for the ftp uploading?
Thanks and regards
