I mostly play what I record, but my friend rents DVDs and doesn't want
to buy any DVD recorder unless it can play and maybe record Blu-ray.

I know thse are hard questions, but maybe you can help me out:

How long until DVDs for rent, the recenly released movies, will only
be Blu-ray?
Is there any point in having Blu-ray now if one's tv is still analog,
or digital but less than 24 inches. (They don't make any hi-def tv's
that are less than 24 inches, do they?)

My friend is concerned that in 2 or 4 years the only DVDs for rent
will be Blu-ray, and she doesn't want to buy a good player now, only
for it to obsolete soon because it doesn't play Blu-ray. How long
before the DVDs she would want to rent, current movies, are only for
rent in blu-ray? If you're not sure, how about a best guess?

How long until the sell things that record Blu-ray at a low price?

If you are inclined to email me
for some reason, remove NOPSAM :-)
