I have had a writable DVD drive in computer for at least five years, only ever used it once to verify that it could write DVDs, worked fine for data.
Thing is at the time I had asked for Xmas presents writable DVDs, I even tried to give them away a few years back, no takers, so they just sat in a box.
For the first time since then I needed to write a video DVD to play on an old DVD player. Linux had lots of options, but the best/simplest seemed to be Bombono-DVD
and indeed there were very few options, it just worked!
I had picked an 8.5gb DVD+R DL RW so if could use it again afterwards.
The disk played fine in the DVD player, but I had added the files in the wrong order and the old DVD player would not let me skip the 30mins of cruft at the beginning and fast forwarding took forever.
Time to rewrite the disk and make sure only the required video files were included ...
Disc with type "DVD+R" in the drive is not clear. Only clear recordable discs can be used for burning DVD-Video. Load a clear one and press OK.
After a lot of googling it turns out rewritable DVDs can not be "blanked" like rewritable CDs and you just have to force the data on.
obviously did not know how to do this and as it is open source I thought I could fix it for them.
After some interesting setup, hacking and execute paths I had it bypassing the issue, Woohoo!
No, the underlying DVD software growisofs
gives "Error 5".
Much more googling and reading Wikipedia DVD+RW
resulted in DVD+RW Alliance
RW is not even explained on their web page
which rather adds to the credence that it was a marketing scam all along.
clap clap clap
I am not the only to be duped
and I doubt I will be the last.
