The Holy Grail, total compatibility, achievable system?

[Cheesus]

I've looked at the compatibility tables & they are a couple of years old now (& so are most of the other ones I've tracked down), so I was hoping people could suggest what is now the best way to make a disc compatible with the biggest percentage of DVD players, drives, consoles. Obviously 100% compatiblility will never be obtainable but by using a combination of the right media, burner, burning speed etc. we should surely be able to nearly obtain that giddy height of total compatibility? :) Right?
I've heard using +R media with the bit turned on for DVD ROM (so the player thinks it is a ROM instead of a +R) helps compatibility. Is this true?
Is a plextor (PX-716A) the way to go with a burner? Is it significantly better than other burners like I've been led to believe?
I was thinking that by providing my clients with both a DVD-R (probably TDK media) & a DVD+R (with the DVD ROM bit thing happening, not sure about media) I'd be covering all bases & should achieve a near 100% compatibility. Am I heading in the right direction or am I blatantly cheating by using two different types of recordable media? ;)

Any comments would greatfully be received.

Yes, book-type set to DVD-ROM helps compatibility.

It depends on who you ask. Varied are the opinions on burners.

(probably TDK media)
In addition to making their own disks, TDK uses other manufacturers for their disks. CMC Magnetics is one.

Memorex BTW uses many different makers for their disks some work for me like the Ritek and CMC, and some Memorex don't work for me like Prodisc. You can use the DVD Identifier Here (http://dvd.identifier.cdfreaks.com/) to make sure of what disks you are using.

I think providing both DVD-R and DVD+R with bitsetting is probably the safest bet. Though probably a bit overkill :) In my opinion, the DVD+R with bitsetting is probably the best. I can even get that to work on my old sony dvd player, which never could play dvd-r's or dvd+r's before bitsetting.
