Need a little help with cdi2nero and settings in nero

[beetle7]

cdi2nero successfully converts my cdi file to an nrg, but when I open the nrg in nero and try to burn it, it give me a warning asking me if I want to use "disk at once" or "track at once". Which method is correct?? I have tried both, disk at once completed but doesn't boot and track at once errored out.

Are there any settings for nero I am missing?? Should I be opening the nrg file or starting a multi session??

A little help would be appreciated, my burner seems to have problems with the 300 sector audio track and the cdirip with isofix and iso extract doesn't seem to work either.

Thanks in advance

Karen
