Nero 6.6.0.6 cd image burning problem

vbimport

#1

I have a nero 6.6.0.6 and lite-on 851S->832S

When I’m burning an image other than .iso - it burns fine, but I can’t open it.
It happens only when nero prompts to choose mode1/mode2 - It happens even when I choose mode correctly(no error mesage after choosing).

Does anyone knows why??? May be I’m doing something wrong???

Any advise will help.
