is there any way that a data DVD originally burned from a mac, then taken to a PC and burned to a new data DVD backup could morph the data and affect the new copy's integrity?
if it matters, i made the burn on "copy to DVD" by VSO software.
in the case that prompts the question, a protools session was saved to DVD on a mac, then the DVD taken to a PC and copied. i don't know yet if the original DVD from the mac works, but the copied one does not. i need to know if there is any way that i screwed up or if the copy i made is sound.
there are too many variables why that disk doesn't play in your PC....... first off ..... Mac and PC are different and some programs don't play on the same format as Mac or PC! Soooooo if that Data disk plays on Mac it might not play on PC. or:
there are plenty of reasons why certain dvds won't play in other players:
1. burning speeds: burn at 4x so there will be less writing errors (rule of thumb is to burn at half the rated speed of the disk--8X disk burn at 4x).
2. read manual for your stand alone player and use the disks that will play in your player. If your player is less than 2 yrs old then it should play the + or - R disks! I said SHOULD that's why you read the manual.
3. try booktyping your drive to DVd-ROM so it will make your +R disks more compatible to players. Read this:

5. use good quality media (rule of thumb....buy the ones that are Made in Japan.) Verbatim is a top notch disk and is the only exception to this rule....some Verbatims are made in Taiwan and they are top notch!
6. and don't burn too close to the outer edge of the disk ..... which will make the disk unreadable! but using good media you will be able to burn close to the edge better than lesser quality media. Just in case I only burn no closer than 4400MB, so if you can set your programs to that, all the better!
follow these little tips of the trade and you'll have better success! good luck.
well, it's not that it doesn't play. it reads fine, and all the data was copied bit-for-bit. it's just that the program that the files were supposed to be read in don't recognize them as files that it supports. it's like the data morphed into something else.
so you know, it was copied at 4x on a 1year old dvd writer on mint condition verbatim DVD+R discs. the original DVD's were mint maxell DVD+R.
and, understand that although the discs were originally burned on a mac and i copied them on a PC, they were never opened in the program in question to make the copies . . . they were just simple burns with "copy to DVD" software.
the question is, is there any rule of digital copying that would alter the data saved by a mac and cloned on a PC that would corrupt the data, all things being equal, so that it would be somehow different on this next generation copy?
(btw, i read your links, thanks, and thought you should know that the last link is broken :)
btw...... the last link still worked for me. maybe along with your disk that doesn't work in the PC maybe some other things don't work!
but just in case...... here ya go....... again ....... the last link:
I'm pretty sure that copying anything to DVD would be ok... weather it was files from Mac or PC.......... games that play on both machines are put on one CD/DVD. Just different operating systems.
the link worked. the first time i clicked i got a weird message from the server. don't remember what it was, but this time, they both worked.
as to the discs, your assessment is right on. apparantly the issue originated with the engineer who originally burned the sessions to DVD:
Quote:This more than likely has something to do the with formatting of the drive that was used for the audio and Pro Tools sessions. Unless a file name has an extension at the end of the name to identify the type of file, these files become orphaned from their creator applications on Windows file sharing (or a Unix or DOS formatted drive). These undescribed files are generically labeled "unix executable file".
looks like DVD technology is in the clear and once again, human error gets to take the flogging. glad it wasn't my error and hope i get to do the flogging, because this has taken up way too much of my time already. thanks for the help, bro.
I've been computing since 1970 when computers were the size of desks and keyboards were built right into that desk! no monitors and only 3 buttons to turn on and reboot adn it had cycles to run..... it also had a punch card input and it would flip through thoughs cards like a knife cutting butter! So when you asked about maybe the Mac had something to do with the PC and the disk..... I knew it couldn't be that! You can basically rationalize anything!
