A month ago I bought 100 DVD-R's from BigPockets.co.uk after copying 1 of the DVD's the others all started not copying and giving errors.
So I updated my DVD-R's firmware to SONY DVD RW DRU-510A 1.1f. However the disc's continued not to work (while a DVD-RW did work - so i knew that is was them not the DVD writer) so I sent them back (thinking it was an incompatability problem - and reading the decription it did mention incompatibility with Sony drives).
I decided to get "Business Special **Grade A Duplication Quality Media** 4x DVD-R" as this sounded pretty fail safe.
I burnt 5 DVD-R's which worked perfectly.
However when i tried to burn the 6th discs the problem sprung its ugly head again.
I discovered that for some discs that gave me an error i could burn at 1x and they would not give a write error.
However these discs would not be recognised in my DRU-510A or my Pioneer DVD-656a DVD Player.
They will be recognised by a Sony DDU1612.
I then found some discs did not want to burn even on 1x speed.
I tried burning onto these discs backups of films using DVD-Shrink and Pinnacle InstantCD+DVD (This didn't work).
I also tried burning using DVD-shrink and DVD-decrypter (This didn't work).
I finally tried using 321 Studios DVDXcopy Platinum (This worked as it played in my DRU-510A - but the DVD would not play in my DVD-656a DVD-Player only).
Something which may be to do with this is that the DVD's I burned with DVDXCopy Platinum were CDFS (Joliet) DVD's not UDF DVD's....??
Do you have any idea what to do...?
I am gonna get a copy of Nero and try with that (and perhaps try copying the Discs with UDF on).
