Stuff not covered by the other...Forii? whatever. General goofiness. (You should not post here unless you've been contributing elsewhere on this site.)
I have a very generic 1 master 1 slave unit that seems to produce CDs and DVDs that play back on other machines if the source and blank discs are at all reasonable. It does take a bit of time to do a DVD.
It has not had anything like heavy duty use, so can't comment on that aspect.
