If and when some of you get your DR1000S, you may find you cannot find the irex companion software.
The manual suggestes it is on the SD card and it is copied across when you format and re-configure a new SD card.
Not on mine
However, a zip file of all that should be on teh SD card is now (all of a sudden) appeared on the irex downlaod site (18Mb). & it does have everything, just downlaoded & checked. It has an additional folder.
Mind you, I suspect the Manual is wrong and that you should always have had to download it.
As I generally use a MAC I hadn't really noticed until now when I am trying to use the PC.
Hope this helps
