As I implied in my first posting I am just passing this info
on; I am not including any thought.  :-)

Seriously, I can't tell from the article why this is the case.
They do note that "DVD-RW format leaves disk formatting up to
the software .... must perform a full disk format  --- which can
take an hour --- before you can start writing to the disk".
Perhaps they feel this investment of time is beyond the
attention span of those who watch TV.  :-)  I can also
speculate that the ability to rewrite the DVD-RW may have
tipped them in favor of it for data. Perhaps all that we
are seeing is the problems that arise when you try to force
data into a tabular format.  :-)

Take your pick/and-or make your own guess!
