I found out that DVD+RW disc must be erased by writing "nothing" to the disc
due to character of random access media which has only one session (one track)
and all its space is allways available. (Nero erases DVD+RW the same way by writing nothing to the disc).
i.e. Last track is not merged and because DVD+RW has only one track, by writing empty track the last track is lost.


Due to this different nature of DVD+RW the free space was showed badly too, because for formatted DVD+RW media all disc space is reported as free (available) regardless of what is recorded on the disc. That is because once formatted the DVD+RW discs become unrestricted overwrite random writable media.
So I fixed it by loading the data from disc session to a image, getting the image size and taking (subtract) it from all DVD+RW capacity. So free space is displayed correctly now.

Another fix is, that sometimes burning could fail, cause there is a need to partially format media before writing.

All is fixed and tested by me.
