I don't know, but it sounds like this DVD has some copyright protection that is creating the problem.  Someone who knows more than me can comment on that.

However - I buy stuff all the time from Amazon.  If the DVD does not work, just return it saying it does not work.  They are very good about this.

Does it happen everytime you play, or was it a one time thing?

Since a DVD player won't recognize it but a computer will, my first wild guess would be that you bought a non-Region 1 encoded DVD.  (You said it might have been through a third party).

Second wild guess, that the disc is counterfeit.  (Third party).

If other discs play, I would try looking at the data via DVD Shrik or some similar.  There might not even be a movie there.

Lastly, I've gotten that error message you quoted and it seems to be a windows catch-all.  In my case, I had thoughtfully deleted my DVD decoder.  Installing a new one cleared it.

It Has Never Played In Anything

Using Opus 8, I Can See The Files So there Is Something On It.

Like I Said Note It Does Not Play In On Of My DVD Players, I have Not Tried It In My Other DVD Players.

It States Region 1 On The DVD.

I have this same set.  I tried DVD-2 and it worked just fine.

Maybe you have a faulty disc.  Does it play in a regular DVD player?

I Did Find DVD Shrink 3.2, And When I Load The DVD, I Can See The Shows On The Preview Screen With No Problems.

If it does not play in a regular DVD player, I would suggest asking Amazon for a replacement.  You process the return on line.  They ask if you a want replacement or credit.  Tell them you want a replacement.  You then sit back.  They will ship the replacement and you can send the 1st order back afterwards.

This may help.

To resolve this issue, Microsoft recommends that you download and install DirectX 9.0b or later on your computer.

When I got that same message, i went to the MSFT windows knowledgebase and looked it up.  It seemed to cover a lot of different eventualities--have a look for yourself and see if anything rings a bell.

just to repeat, I got the message when I had (smartly) deleted my own DVD decoder.  The decoders have all the keys for this really useful CSS scheme, so if there is a problem with your computer talking to the decoder, it will throw that msg.

However, it sounds like the disc is having trouble doing the key exchange with the decoder.  if everything is region-1, and you've tried everything else, I would use DVD ShriNk to rip the disc losslessly and burn an new (unencrypted) disc, and Bob's your uncle.

Randy--

Looks like you went to the knowledgebase.  I think the only ointment in that fly is that the disc bombed out on a hardware DVD player, in addition to showing that message on a computer.  So I think the disc is no bueno.

I think you are right, but it looks like KingSparta wants to figure out the message.  I would just try to return it.  All Amazon can do is say no.

I've had bad CDs in the past and was able to copy them.  The copied ones would then work.  So your suggestion may work.

The DVD's Are Out Of The Return Policy Window, It Was Also From A 3rd Party, And The Return Policy For Amazon.Com 3rd Parties Are Not The Same As Buying Direct From Amazon.Com

So It Can't Be Returned.

DVD Srink 3.2 Ripped The DVD Without Problem

MC12 Will Play The DVD Ripped With DVD Shrink 3.2, But Not The DVD It's Self.

I Am Going To Try My Other DVD Players Now
Title: Re: What Does This Mean - Key Exchange for....
Post by: KingSparta on March 31, 2007, 02:19:20 pm
The DVD Plays In My 300 Disk Pioneer DVD Player.

So to Me This Means There is A Problem In the Firmware (Maybe) Of My DVD Player From Mintek.

Also For Some Reason MC12 Refuses To Play The DVD With That Message Above.

I Noticed That The DVD Has Files Called VTS_01_0.BUP, That Are A "Backup Up File Of The IFO"

Is It That Some DVD Players Read The "Backup Up File Of The IFO" When There Is A Key Missmatch. And MC12 Maynot be Reading the "Backup Up File Of The IFO" When It Runs into A Problem With The Key?

So The DVD Seems to Play Fine In All Software tested But MC12 And Windows Media Player.

And One Of My DVD Players.

Why?

Post by: Matthew on March 31, 2007, 03:54:12 pm
There is a program that is guaranteed to work with this problem it's called AnyDVD.  Hope it works. :)

Note The "Found & removed invalid VOBUs!"

What Is A invalid VOBU?

Quote
The next higher logical structure is called the Video OBject Unit, or VOBU. Each VOBU starts with a NAV pack and contains approximately half a second of the program. The size of the VOBU is determined by the video coding unit called a Group Of Pictures (GOP). A VOBU will contain one or more complete GOP, as needed. The last video pack in each VOBU is padded if needed with either a padding stream or stuffing bytes. Audio and subpictures with DTS values within the same range of values as the video are included in each VOBU. Audio is not padded until the end of the cell, therefore audio frames can span VOBUs.

Maybe Why The DVD Does Not Work In MC12?

Maybe That's Why Other Users Have Had A Problem With Other Dvds And MC12 And (Maybe Media Player).

Not Sure Why I Would Need To Spend $49 To Watch A DVD That Should Work Anyway (I Guess Something Went Wrong When Burning The DVD At Universal Pictures Or Who Ever They Contracted It To), But I May Buy It Just So I Can Get Around Problems Like This.

I Think It Is Worth JRiver Investigating This Problem if It Does Not Have Legal Issues, But This Is Not A Homemade DVD.

AnyDVD looks interesting.  It appears to have the same basic functionality as DVDFab Platinum which is what I use.  With DVDFab Platinum I can copy the movies to the PC and also create mp4 versions for my iPods.  Like AnyDVD it can strip out all of the copy protection (note: I only backup for my own use).

One option would be to use AnyDVD or DVDFab to copy the DVD to your PC.  You should be able to play that with MC.  You should also be able to take the PC version and burn another DVD. If you use their trial versions you could at least fix up your Columbo DVD without paying $49.

Post by: KingSparta on March 31, 2007, 06:17:56 pm
Well It Is Really Not A Money issue

I Did Use The Copy Fuction And I Noticed All The Files Were The Same Size But 2

VIDEO_TS.VOB And VTS_01_0.VOB

Maybe they Are the Files On The DVD That Got Messed Up When It Was Burned At The Factory.

I Did Disable All Fuctions Of The Program (Regarding Copy Protection And Regions Etc..) And It Seems It Still Corrected This Invalid VOBU Issue.

If Other DVD Players Correct For This Issue (If The Problem Is The Invalid VOBU Issue) MC12 Should Also.

I have run into simalar problems with CD's where the problem was a bad pressing.  Like vinyl the dies wear and this disc of yours could have slipped through QC.  I have been successeful in using Plextor Plextools (you will need a high end plextor drive) to QC the disc.  It will actually chart by location all the defects on the disc.  I have been able to demonstrate that the disc is defective with these charts and I have recieved a replacement from the seller right away (even when it was past the return date).  I buy some used CD's at a very reputable store locally and I check them right away for defects if they are defective I return them without any hassel.  This should be effective with the manufacturer as well but the problem is finding who to ship the disc to.
