IIRC, the DVD standard makes use of multiple layers of opaque encoding as 
well, at various angles that the CD-RW simply might not be able to achieve 
at their low manufacture price.  Hard to say - while there are certainly a 
number of drives out there that can read both media (such as in new 
laptops and such) I don't expect the burners for DVD to come down "real 
soon" in price.

As for cross compatibility, I think it would be a myth.  If nothing else, 
it's being mis-marketed if it _does_ exist.  A CD-RW that can burn DVD's 
would be better marketed as a "DVD-R that can also burn CD-RW" if you ask 
me.

/me tosses two bits on the table and takes a swig.
