I have so many that I know I can't sell for anything and want to remove because they take up space and I am lacking that now.

So what do you do with the previous versions that are rendered pretty much obsolete because of a double/triple dip?

Trade them in. Ebay them.

Amazingly, I've only double dipped a few times, some I've held on to cause they may have an extra or something that the DD lacks, so I keep it as complimentary DVD to the DD.

The other few I just give to my brother...

I've held on to my The Good, The Bad, and The Ugly original release simply cause I didn't want an empty slot in my Man with No Name Trilogy Box set and the DD doesn't fit.

I've only double dipped 3 or 4 times, gave the old one to a friend or family member.

Trade them into Amoeba records and buy more stuff.

I put them in storage with the other crap I don't watch.

Give them to people I don't like

I give them to the old man or brother. Giving to thelibrary is also a nice (and I believe tax deductible) way to go.

I trade mine in to FYE I got $4 a disc...Woohooo

I've been giving them to my mom.

Well with sites like this, I find out months in advance, so I eBay them to unsuspecting J6P

Give them to my nephew if it's PG-13 or less.

Sell most on Half.Com or Ebay. Sell some to the local dealer at the flea market (pays $8 each for titles that he needs). Even if I don't get but a few $ for them, it is better than having them sit around and never be watched again...

Also, there are some that I keep because of extras that are missing between the two versions... Ferris Bueller's Day Off and Silence of the Lambs Criterion come immediately to mind. I have the newest version of each, but the old extras (commentaries, etc.) are too good to let go.

I have an out of the way storage place (under the TV in my computer room) I stick them along with various tins and other packaging I don't really want to waste space on. I probably have 10-15 or so. I don't really like to rebuy stuff, but I'm a sucker for things like the Ten Commandments or Maltese Falcon where you get other versions of the movie.

I would never get rid of that one anyway since I somewhat prefer that cut of the movie (some of the new dialogue is really grating to me). That one stays on the main shelf with the other Eastwood movies.

Give them to family members.

Unless they contain extras I can't live without, I eBay them. I've been able to get rid of almost every SD-DVD that I've upgraded to HD-DVD. Unfortunately I won't be able to do the same with Blu-ray since they routinely drop many if not all the extras.

Mostly I sell them at a CD-DVD exchange place or I occcasionally give them to family.

I have the same problem. Does anyone know if either Fry's, Best Buy or Walmart buys back used dvds?

Those are retail stores, not used DVD stores.

One place that buys used DVDs is www.secondspin.com though don't expect top dollar. Your best bet would be ebay.

Someone mentioned that Ferris Bueller DVD and I held on to the old copy as well, but what I did was combine it using an empty 2-disc case. Did the same with Daredevil (theatrical/DC), Mr. & Mrs. Smith and a few others.

Sell, trade, give away...However, now with HD-DVD I have some dvds that Im not sure what to do with. For example, I have Batman Begins with the comic and a sealed wide screen Corpse Bride from Wal-mart with the Lenticular cover that I cant justify trading in but will never do anything with, so trying to figure out what to do with it.

Personally I put my extras together and Ebay them as a lot. I can't stand selling them one by one on Ebay, alot of time to list and little payoff...

Get rid of them on Amazon.

If you itemize your taxes give them to a library and take the write off. It doesn't give you cash in hand but IMHO it's relatively easy compared to the hassle of listing them, dealing w/ shipping and then wonder if the buyer is going to screw you somehow.

DVDPlanet for store credit, use the credit for Criterions...
