401s + Nero6 + dvd-video + stand-alone = working?

Should 401s be able to burn working dvd-video discs with nero6 ( - now obviously updated)? I’ve burned stuff to my friend’s Pioneer stand-alone - +rw dvd-video worked well, but have not tested with +r media.

Question arises as my friend got problems to view (not recognized) his LG-4040B made dvd-videos (verbatim media) that he burned with same Nero version than I.

If someone can give me any information in this one, I would be very grateful, thx.

I would not want to ruin many +r discs if there is another burning software that handles that media better.
