[Bug 2035093] Re: "Invalid argument" at burning DVD

[Paolo Berti]

HELP FOR A RESOLVE
The bug is described and a diagnosis is given here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=794868

It gives this patch to the growisofs_mmc.cpp file as a definitive solution:
________________________________________________________________________
-	if (!(errcode=cmd.transport (WRITE,(void *)buff,size)))
+	if (!(errcode=cmd.transport (WRITE,(void *)buff,nbl*2048)))
	    break;
________________________________________________________________________
In the source package of dvd+rw-7.1-14build1 (used by Ubuntu 20.04.6), the file growisofs_mmc.cpp has, at line n. 527, exactly:
if (!(errcode=cmd.transport (WRITE,(void *)buff,size)))
So corrected as above can resolve the bug.

I am not a c++ expert and am not able to do it by my self.
