I noticed that this issue, "How many of you have stopped buying DVDs?", in some ways boils down to the DVD owners versus DVD renters.
I am a HUGE fanatic about owning things. I hate to rent. However, I can definitely understand why many of you want to rent DVDs (e.g. NetFlix) In fact, most of my friends and relatives rent DVDs rather than own. Part of the reason why I have to own is a psychological problem. I collect things as small as sunglasses and watches to things as large as cars and houses. It's not pretty.
And I think that with the new Hi Def discs (BluRay or HD-DVD) there probably will be some advantages to renting---
a) If you solely rent, even if "your" format loses, the most you're out is money for the player as you'll have already enjoyed all of the movies you rented.
b) With prices in the mid- to high-twenties, it would be godawful expensive to accumulate 2,000+ new Hi Def discs.
So, unless something changes, I'll probably wait 2 - 3 years before I start buying Hi Def discs, the logic being---
a) Hopefully, the format war will be settled (in some fashion)
b) Prices will have come down and we'll be able to buy USED Hi Def discs
c) I'll be bored of my current DVDs and will definitely be ready to start hoarding a new medium
