Thanks a lot for your reply, I now changed the minimum segment size to 1mb. I'll test it as soon as I've another computer available (arround 17:00 today).

The other thing I wonder why so few downloads reach "Completed" status and why so many hang at "Downloading 100%". Does this have any impact on phex or on the files, or is it safe to ignore it?

Thanks for your patience, lg Clemens
