recently tried to play copied dvd on dvd player some would not play with bad type error but they all played ok on my pc and laptop. Did the usual change of media even bought a new dvd burner and different software but still same problem then i looked at the volume label of my copies that played and those that did not i noticed any that had the underscore character or numbers in did not play in the dvd player when doing a strait copy it takes on the label of the original So as a test case i tried reburning a copy again as before and tried it and it was not playable in the dvd player as before Then i did a copy of the copy which did not play in the dvd player i changed the save folder to a single name similar but not the one suggested by the dvd volume and i stopped the process after the vob files had been created on the hard drive I then started nero and burnt the vob files as before but this time in nero before burning i set the volume label of this blank dvd as NEW the nero default and like magic this next copy worked in all the 3 dvd players we have and the pc ok so it seems dvd players are fussy about the volume label they read at start up so dont go changing media and the like before trying setting the volume label to a single name the other working dvds were on the same media but had single names as their volume labels its worked for me so this dispells all the rumours of bad media and burner problems and software problems as i tried them all and still had the same problem that problem has gone now i have just single name volume labels on the dvd i could experiment more but if it works leave it alone i say So check the volume label of your dvd that dont play on the dvd player but are ok on a pc to see if what i say is correct post a reply if it works for you too
Is it definitely the underscore or numbers that cause the problem? Nero has a history of problems with volume labels over 16 characters and A-Z, 0-9, . and _ are standard characters.
the volume labels that did not run had underscore characters between the label names and the other one was a mixture of characters and numbers i reburnt these from these bad copies only this time with a single volume name and they both now work in all 3 differnt dvd players and on my pc so it seems something happens in the dvd players or in nero when these are used maybe nero inserts some hidden chrs that the dvd player cant read ive always used dvd shrink and dvd deycrpter and nero this problem has only just started to happen with latest dvd and all i could find different were the label names on good and bad copies as if you let the software do the burning automaticaly it takes on the original label name maybe this is some inbuilt anti copy system who knows but i know this fixed it for me
no they did not but one was volume label P9260S the other was 11 chrs long in capitals with an underscore and the number 3 in the volume label all the others that worked i burnt as volume label NEW or a normal name its strange why this should be the case but it definatly works to solve my problem i was having it may be something to do with nero and the way it handles volume label chrs that would explain why its a bit hit and miss with the success rate with people burning copies it certainly had me confused thats why i went and changed burner and media after reading the forums and still had the problem even wondered if i was using the correct burn method but the working ones ruled that out One thing i did not do is a copy of the bad disk and renter the original volume label as i do the burn and see if that makes a difference may try that when ive more time only after comparing the working and non working ones did i find that the volume label style seemed to be different so gave that a try and was successful even using the bad disk to copy from so that ruled out a bad burn maybe someone else who knows the program better will know the answer this may cure other people with the same problem or maybe its just my setup gone loopy who knows
hi finally cracked the problem using VSO inspector i looked at the sectors on the dvd and when comparing a good copy with a bad one I found that at sector 16 is stored the dvd label and this is as it is for both good and bad but then at sector page 32 on a good disk it is the same again but on the bad disks every chr is padded with a decimal point hex 00 and again at sector page 33 and so on so nero or the something is putting in hex 00 between each character in the label name so on a good disk it reads BAD BOYS on a bad disk it reads B.A.D B.O.Y.S so thats the reason for them not playing on a dvd player but ok on a pc why this is i dont know yet going back many years i had a problem like that once before when changing up to dos 6 and using an eprom programmer program and that went wrong as spaces were padded out by .full stops in dos 6 that couldnt be read by the programmer so i had to apply a fix maybe this is some new simple but efective copy protection or just a glitch with nero regards steve
