Here's what a guy from Philips said: "This is a known issue which is already solved. The problem was, that 3 ECC blocks after the VOB files, but before the VTSI BUP files are left blank. This is not a problem for playback, but 1 to 1 copying cannot be done easily..." You must copy the files from the DVD to a directory on your harddisc, then use IFOEdit , VOB Extras to correct VOB files. Close and reopen IFOEdit und recreate IFO files via GET VTS Sectors. Takes some time but afterwards you should be able to to whatever you want with the files. Good luck Alex
