Special Effects/Soaring vistas type films I will only buy on Blu (or replace my dvds).

But other films, such as dramas/romantic comedies I tend to buy the cheaper DVD version (when they hit the sales for £3-£5 or so).

To date the only TV show I've bought on Blu was Being Human Series 1; but generally speaking I think TV shows are way too expensive on Blu (eg. I just picked the R1 version of Heroes Season 3 on DVD for £15.00 including shipping...the UK BD would cost me £40+. Not really feasible IMO).

Initially I said I wouldn't replace any of my DVDs...but as time's gone by I've found I can't resist when I can get a bargain (recently: Hairspray for £2.85 and Fantastic 4 for £3.98).
If I had the money I would probably replace every film I could...but I don't...so I can't!   

Older TV shows, low budget movies and documentaries (except the Planet Earth type available on BR) I still get on DVD. But most of my new acquisition are BR only.

I buy tv series and bargains on dvd. Depending on the price performance ratio, I buy new movies on blu-ray!

I picked 'Yes, when HD won't matter as much.'  Because of the price, I only purchase Blu-ray discs when HD is an important aspect of the film.  If, however, the Blu-ray is on sale, then that rule no longer applies.  Most of my Blu-rays cost less than $20.00.

^ This.

I find that only if I truly want the movie.  I have picked up a few that I own on DVD, but like others, I will not collectively upgrade y collection.  A few here or there yes.

Is tend to look for the combo if I can get them.  I have 2 BD players in the house, a stand alone, and a PS3.  Otherwise, I still have 6 DVD playerr in the house, and 2 in the vehicles and a couple of portables for the kids.

I will probably purchase a majority of DVD's for a while.

Well DVD/BD Combos seem to be the best choice for you.. It also seems that more and more companies release those... Maybe for that exact reason..

I, myself, try to buy BD only Versions, if they are cheaper, since I don't need the DVD's anymore.. I don't have a DVD Player in my Car and I have 2 BD Players, one in the Living room and one in the bedroom.. So the only place where a DVD would make sense would be the PC Coner but I rarely watch movies there..

If it's a movie my wife and I both like, I'll buy both the BD & the SD.  I just ditch the Digital Copy from the BD and put the SD disc in it's spot.  If both versions are the same, SD it is.  If my wife doesn't care for the title and there's more features (other than the stupid BD-Live), BD it is.

I've been buying a lot of blu's lately.  The only time I buy DVDs are now are if they are really cheap, like less than $3 a piece and if it's something I don't think I'll want to double dip on.  I've also double dipped quite a bit and then sell the DVDs to try and recoup some of the money.  In some cases the DVD has content that didn't make it on the Blu-ray I'll hold onto it as well.  Or in some cases, I like the movie & edition of the movie so much I don't want to part with it.  An example is that I bought FIght Club on Blu-ray but I have no plans on getting rid of the CE version of it.
