OT: DVD long term problem

I have done a search on the forum but can't find the answer, here's my latest . I use RiData or Taiyo Yuden DVD-R to burn no problems but now it seem a year or more later I have complaints of disk failure, anyone else get that. All my DVD's are done DVD Studio Pro basic menus etc. The main complaint would be DVD stops or skips during play back, I ask the usual are they using a different deck, is the disk scratched or clean? Anyone else get compalints down the line?

What is the encoding bit rate that you normally use?

Home burned DVDs use about the same technology that color photography does. Leave one in the back window of your car in the sunlight and it's history.

We've had two year old shows burned properly on very good quality disks that no longer even mount in a player.

Home burned DVDs are not a good place to put archival work.

I make my DVD 1 hour long Target bit 4.0, Max 7.0 file size around 3 gig.

So for Wedding archival DVD's? what do you recommend Koz.....price and time is always an issue. Would I go to a service and have a master burned, whats the best way to archive?

Also when reading tech mags like photo's I've read good quality DVD's home burnt should last if stored correctly past our life time, obviously not.

The ones where the movie is burned into the aluminum layer as pits probably will last years and years. The ones where the movie is burned into the dye layer as discolorations may or may not last depending on whether or not the burner knew what to do.

There is a "home track" on DVD-Rs where the maker of the disk is announced as well as characteristics of the dye layer and how best to burn it. The options are everything from leaving no mark at all to incinerating the layer.

The Pioneer drives know exactly what Sonys and RiTek/RiDatas are and they work really well. Unfortunately, if the burner has no clue what to do or it doesnt recognize the track, it defaults to a "generic" burn which works most of the time. Those are the ones that will kill you; if not now with cranky clients, then later when the dye layer fades.

There is a program that will read that track, but it will remain a mystery until I can get to a machine.
