Product functional installation difficult

After back and forth the customer recessions I would like to sometimes give my opinion on this product.
So the device is working, if you have struggled through the chaos of the installation. When you first start the software, there are a bunch of error messages and nothing goes. After 30min play around in the configuration you then picture and sound on the screen.
The manual can thereby forgettable. Apart from the name and safety information is there is not really much inside.
The quality of the recordings satisfies me, my claims are with my 10 year old bands do not really high.

System is WinXP with SP3 on a Centrino Notebook (2GB RAM)
