yeah, sounds like unclear manual assuming your video file also in /tmp, try same steps but with next line you tried first (or delete already written  stuff from /mntX before next try)

Just to add, I have several DVD and BD discs with video written earlier using various tools, CinGG/bdwrite, K3b and NeroLinux, but probably none using just this procedure for HDV:

I repeat and continue from step using a blank DVD+RW disc:

bdwrite /mntX 20081103140154_m2t-eac3.m2ts

tree -h /mntX
/mntX

# If so, what should it be for a 4.7 GB DVD+RW?
