After months and hundreds of medias, these are my conclusions,
please add your comments.

1. Home burners, no matter brand, model or media,
youŽll never get a 100% compatible DVD to play on desktop players.
This is because there isnt a 100% compatible standard between players manufacterers. So, in the best situation, you'll be able to whatch your DVD on 30-50% of players fine, but youŽll have problems on the rest,
and (this is important) the problems you experience on one player will be different than on others. What means that the problem is not (only)
on the media-process itself but in the "way" is read by players.

2. Plastered labels on DVDs, same thing, but this reduce the probability
(or number) of players that will read your dvd without problems.
Definetely, most players (but not all) have problems reading dvds with labels.


3. Medias, most bad/cheap medias has their problems on the external half.
So whatever you burn below 2 GB, it's unlikely to have problems,
that's why some cheap medias could seem normal or good.
When burning around 4GB, you'll see the difference between
good and bad medias.


4. Recording Speed, it's related to point 1.
The slower the speed the easier to be read by players without problems.
But (and please help me on that) is getting harder to find medias
accepting 1x or 2x speeds. Or, thereŽs something worng with Nero,
because when you insert the blank media, the speed options change automatically (usually to x4 or 8x) and thereŽs no way to change it...

5. Industrial medias
I've seen that factories dedicated to duplicate movies
professionaly in large numbers, produced also a type of media,
which will hardly work on most home burners, but when
burned on special "multiple" duplicators, produces a high compatible dvd.
This reinforces the idea that there is a problem with reading standards
between player brands.


Resuming, all you can do with a home burner is to increase
the chance of the dvd to be readable by players, but even on the best situation (brand,media, speed) a big number of players (30-50%)
will have some problems. Remember that this "problem probability"
will also increase above 2GB contents.

Regarding the Nero problem, it should be correctable by updating to the latest version. I had the same problem with Roxio, only 4X and 8X selectable even when using up some old 2.4X disks or trying some 16X. I had to purchase the newest version, but it now reads properly which media and the speeds at which I can burn.

It's true also that slower speeds can help insure a successful burn, but there's such a thing as "too slow." I regularly burn 4X on 8X media and almost never have playback problems when testing on many players. Even burning 8X on 16X media works perfectly between my various DVD-ROM drives - I haven't yet tested those on standalones.

Although you may be correct to some extent (but I doubt your suggested low 30-50% compatibility), in theory, this problem can be overcome by burning DVD+R media with "bitsetting". This supposedly makes the burned media appear to any and all players as a DVD-ROM (pressed not burned media) that all players with a "DVD" logo must be able to play.

Even without bitsetting, I personally have had a significantly higher success ratio than you've described. I periodically check burned DVDs on players at electronics stores...

Thanks

1. Isn't it that only some dvd players accept dvd+R?

2. What rate of compatibility would you say you have
(maybe 3 out of 4 players)?

3. What is bitsetting? What program? What speed? What media?

Isn't it that only some dvd players accept dvd+R?Almost all players made in the last few years will accept DVD+R movie ROMs if bitsetting is used. In fact a friend of mine has a player that was specifically listed to not be able to play back burned disks at all, and recently he has sucessfully burned and played some on it using Nero 7 Ultra. Bitsetting is enabled automatically within that particular program.

What speed?Already mentioned above, never more than half the rated speed of the drive or the media.
