Has anyone tried any DVD-R DL discs yet?

[Carlos Garcia]

I see Verbatim now sells DVD-R DL discs as well as their original DVD+R DL recordables. Has anyone tried any of the DVD-R DL discs yet? I'm wondering whether these discs play as well as the DVD+R DL. I originally read that DVD-R DL didn't have as good a reflectivity reading on DVD players as DVD+R DL discs have, so they might not play in as many players, or might encounter more problems. Anyone tried any of these discs yet?

Yes! Avoid them!!! There are big problems with the layer break placement. And, IMHO, the quality of the -R technology is not as good as +R.

For more informations, look here (http://forum.doom9.org/showthread.php?p=674722#post674722), and, later, in the same thread, here (http://forum.doom9.org/showthread.php?p=678298#post678298). (This thread concerns PgcEdit 0.6.0 beta's burn DL DVD function, and is very technical. The problem with -R has been discovered in Japan, so, there are many messages difficult to understand. Look at the messages posted by jinjin_jp, and the answers...)

I agree with ro1z. Avoid them.

I tried verbaim DVD-R DL

Ironically they play in my dirt cheap player and my 1998 sony but refuse to play in my Panasonic DVD recorder

Where as DVD+R DL disks play in my panny, but not the other two

[atreides93]

I'm surprised your 1998 sony can play a dvd-r let alone a dual layer one :)

I have yet to try a dual layer dvd+r or -r...maybe one of these days when I'm feeling bored. Oh ok I guess I'll break down and buy a pack.

Hi,

Can anyone tell me / or show me if These DVD-R DL discs are OTP (like +R DL) or are PTP?

Thanks,

Borgster.

As far as I know, all DVD+/-R DL discs on the market today are OTP.

They are OTP but in my experiance unlike DVD+R they write all the way out then all the way back. All the space on L0 is written to then the remaining data is placed on L1. Any remaining space at the end is nulled when the disk is finalised.

I assume this could eliminate the problem of having L1 bigger than L0, by simply nulling the remaining space on L0 to keep layer breaks in the same place.

Perhaps somone with a more technical insight could answer this one for us.

You're probably right. DVD-R DLs are using the whole L0 for datas! This is unbeliveable, as it will force the user to write the DVD completely (this is not DVD-ROM compatible), and the outer edge (which is often of poor quality and subject to scratches) will be filled with data.
IMHO, the DVD-R DL standard is pure bullshit. Avoid them!

This thread (http://forum.doom9.org/showthread.php?t=95250&page=1&pp=20) discusses the problems I've had with DVD-Rs to write the DL burning routine of PgcEdit. It tooks me a while to understand why the first layer was always filled upto sector 2092896 with DVD-Rs... :angry:

@BSpielbauer
Are you sure that the layer break position has not changed? That's in total contradiction with what I've seen: the layer break seems to be always at sector 2092896! Could you verify with DVD Decrypter?

Also, note that the DVD+R DLs were available far before the -Rs.

Oops... you are, of course, correct. I thought about trying to edit my original, to make this clear, but then I realized that my original post is completely irrelevent, given the original topic of this thread.

My apologies for all confusion,
