Not buying DVD's anymore since April 18, 2006, the date of the first HD disc releases, "Cars" and "Pirates 2" in HD is foremost on my purchasing list, along with "Casino Royale".
I've been amazed at being able to resist buying all these first run movies that have come out on DVD already, probably only by constantly thinking how crappy the DVD movie will look blown up 110" on the Home Theater screen.:rolleyes
1) Watchability and rewatchability 2) Comparability 3) New features - this includes New sound or enhanced sound 4) Noticably better picture quality (hasn't been an issue thus far!)
I double dipped on Constantine, a not great movie that I doubt I will watch too much but it had a WICKED Dolby True HD soundtrack which made the purchase worthwhile.
I doube dipped the Sting becasue it is one of my favorite movies of all time and I just bought the SD DVD last year sometime.
I double dipped the Searchers for the Picture quality.
Double dipped Batman Begins for just about every reason on my list.
Double dipped Serenity because I liked the film and the HD DVD just shines!
Most of the other films I have purchased were either for curiousity (never owned or never seen - Lethal Weapon 1 and 2, Mutiny on the Bounty, Robin Hood) or were new releases - Superman Returns, Babel, the Departed etc)
I have not watched many SD DVD's since I got my HD DVD player. I like the player and the movies in HD that much.
1) Do I really like the film/TV show? 2) There is an improvement in picture and sound quality. 3) Correct aspect ratio 4) Watchability and rewatchability
I most likely would not double dip non action and non sci-fi movies if I allready own a good quality copy on SD-DVD.
Movies like Back To The Future, Pirates Of The Caribbean, Star Wars, James Bond, Matrix, Crimson Tide, Jurassic Park, Hunt For Red October, Saving Private Ryan, Gladiator and Master And Commander will get purchased again in HD.
Good quality suspense/horror flicks will get repurchased in HD
I have basically stoped buying SD-DVD's as I would rather buy HD titles. I do buy SD-DVD but very rarely and if I am weak and have to have a new release.
So basically I will only double dip the titles that I really love and I will keep the other titles on SD. Besides not everyone can go out and completely rebuy there movie collection every time new formats come out. :frowning:
Mine is narrower than Dave's criteia. 1) Does it have an improved audio track that is an improvement and 2) Does it look better. It already has "rewatchability" if I am even considering double dipping. New or cool extras can be a plus too, but I haven't found there to be much in the way of "new" extra features so far.
I will be more selective in HD (gotta keep telling myself that), but I will absolutely refuse to buy anything on HD that is not sourced from film or HD video. Open Water could come with DTS-MA audio and I still wouldn't double dip because the original film is sourced from DV. Same with Bamboozled, Borat and a host of others sourced from DV. Sin City is going to look INCREDIBLE!!!!!!!
For the past couple years I've slowed way down on SD-DVD to avoid double dipping. The titles already in my collection will have to have picture improvement, and have to be among my favorites. I won't be replacing anything I bought way back in the dot-com craziness that I bought just because they were cheap. Also, depending on cost. If I can sell my SD-DVD and upgrade to BD without a huge outlay, I'm all about it.
My criteria are flexible, but the general rule of thumb I use is that if the HD release betters an SD release that I own as a complete package - extras included - then I'll buy. I'm more laid back about new releases & things I've not owned before though.
Generally, the higher the AR, the more difference in video quality HD provides on a large screen. Hence I am more likely to double dip on 2.20:1 and higher AR films assuming I have the DVD and enjoy rewatching the movie.
For the most part, the format war doesn't enter into the equation as I have both HD DVD and BD.
Some of the early discs left someting to be desired in image quality, but all of the more more recent releases seem to be a major step up in image quality over the DVD.
My criteria for image quality is fidelity to the original release. For example, if the original was shot on a grainy film stock, then I am expecting to see an accurate reproduction of that same grain. Titles using excessive (visible) DNR and grain removal destroy the original look of the film and are not a rebuy candidate.
