can anyone help me with figring out how to burn these files to DVD?

i have downloaded both the 'in memory to brian jones" & 'new barbarians" dvds but they are not 'iso' files. when i try and drag them into windvd creator or nero some of them work and others don't. the menu doesn't work but it's there. should i be converting these 'vob" files or using a certain program??? i downloaded the fenway discs and since they were iso files they burned directly to dvd with no problem...any help would be greatly appreciated.

thanks

Hey there - you need to use a dvd authoring program. I use Adobe Encore at work, but it's expensive. There may be a trial version or do a search for dvd authoring software. Good luck.
