Finaly, I found an (German) Tool for downloading the tracks without the need of the PhotoTrackr software.
The name of the program is iTrackU - Tool V1.12
Original is it writen for the XaiOx logger, but it works also for the DPL700.
I tested it with my DPL700 firmware 4.2, and it works 100%.
This tool run only on a PC. (XP and Vista)
No registration required, so you can use it on more than 3 PC's. download iTrackU
Edit: you must install the PhotoTrackr driver on PC.
