Hello Fellow PD8 Users,

I made 21 DVD-DL (Dual Layer) disks for the parents of our 7th and 8th
grade basketball team. A few of the parents complained that the DVD
stuttered so badly that they couldn't watch the game with any enjoyment.

At first I thought it might have been an issue with the PD8-produced
MPEG-2 DVD's not burning properly across the entire batch. So I made
myself and DVD-DL of the game put it in my home DVD player. Lo and
behold, the video stuttered, and even started over a few times. I've always
"proofed" my PD8 produced DVD's by watching them on the computer.

I called 5 parents who were experiencing the problems and found out that
they have DVD players that were made in 2004 and sooner. My DVD
player is made in 2002. 2002 doesn't sound like it was that long ago, but
apparently in terms of technology, it's ancient.

From what I've read on various websites today, the Dual Layer
DVD-DL DVD didn't become available until 2004 and it was very high
priced.

The desktop DVD players produced in 2004 and sooner usually do not play
DVD-DL disks. The movies produced by Hollywood in the early part of
this century were DVD-ROM Dual Layer, which works on "older" DVD
players and could hold a 2 hour movie.

Am I correct in my understanding of WHY DVD-DL video won't play
properly on older (pre 2005) DVD players? Has anyone ever seen
a DVD-ROM Dual Layer DVD? I looked at Walmart tonight and couldn't
find such an animal. Perhaps first I should check to ensure that PD8 and
my HP burner can make a DVD-ROM Dual Layer DVD.

I have a 2002 Pioneer DV353 and it handles them fine. I'd look at http://www.videohelp.com/dvdplayers for a few players that have the issue and see what others report overall on play capability. You should also note that many more players are compatible with DL+R than DL-R. For older players you may have to change the audio to LPCM as well. Make sure you are using a good quality DL disc as well.

You cannot burn to a ROM. It stands for Read Only Memory and can only be read once it leaves the manufacturer. Our Walmart does not carry any dual layer discs, but what you will find is DVD-DL, or DVD-RAM which is an entirely different creature and works like a floppy disk drive, except very slow.

It is possible that some players that predate the dual layer disc may not read them as the layers are overlayed and the player has to be able to read through the top layer. I'm afraid I never owned one of the older players and can't say for sure.
