RE: [Dvdrtools-users] Sony DRU-500A DVD-RW - command sequence error

[Scott Prive]

Hi,

I might be telling you something you already know, if so don't be offended ;-)

When you say you had a "successful" burn, but the DVD Video player does not 
recognize it... there can be more than one way to fail in a DVD Video player, 
so I am curious as to how you determined it's the disk? 

It very well might be the drive cannot read DVD+RW (in fact it's most likely), 
but the other possibility is the "authoring" is somehow noncompliant.

I say this because I once made a DVD-R that played on the computer DVD 
software, but not on the Video Player. It turned out I had illegal pointers in 
the IFO files, which the computer didn't care about but the standalone player 
did. There are, of course, other ways to confuse a DVD Video Player (lowercase 
files, etc). Video players don't seem to have "real" filesystem support, and 
make many assumptions about file structure.

All reports seem to be that DVD+RW/+R is less compatible than DVD-R -- and I'm 
convinced of this myself -- but before you conclude the format cannot be read, 
you might want to test some more.

Two tests I can think of:
1) Do a 1:1 disk copy of something that plays on your DVD player. 

2) Author again to DVD+R. On EITHER side of the DVD "format war", the 
write-once media have higher compatibility.

Hope this helps,

Scott
