I had a Veho scanner for a short while, and I suggest you don't get your hopes up too much even with better software. Colour negative films all have different orange masks, and the Veho I had knew nothing about that. See if you can borrow a scanner that's attached to the computer and controlled by software on the main computer, you get much higher levels of control.
Basically the Veho I had was a fairly rubbish 5 mp camera in a non-light-proof box. The quality was dire, the upside was it was very quick compared with the better options from Epson, Plustek, Reflecta, Canon etc.
