Not sure if this is possible or not. I've got a dvd with 5 music videos on it, and have recently come across 2 more by the same band, also on dvd. Is it possible for me to add the new videos to the original 4 in order to make just one disc. I tried renaming the ifo, bup, and vob files to 6 & 7 and burning with Nero, but I got an error message of "Dvd-Video files reallocation failed. The resulting Dvd-Video might be unplayable. Do you want to continue?" I'm guessing that the problem is with the Video_TS ifo, but I may be way off. Any help would be greatly appreciated. Thanks. cagerage
