Thanks for another reply. So obviously it is better to burn straight after the conversion. If I convert files seperately then I can only burn 1 to a disc. Waste a lot of discs that way. So if convertxtodvd cannot burn the files after converting to DVD do you know of any program that does this? In essence I would then need to burn multiple DVD files to one disc.
Maybe more explanation of what happens is needed. ConvertX writes a folder to your hard drive that has the same name as your first input file (you can change names of input files in the asset window before conversion if needed). It also writes a VIDEO_TS folder inside that one that is required by DVD standards. The VIDEO_TS folder contains VOB files that contain all video and audio content, IFO files that give a player playback info, and BAK files that are backups of the IFOs. The VIDEO_TS folder and its contents need to remain as written to comply with DVD standards.
There is a set of files in VIDEO_TS for each title in your production, i.e., each of your input files. There is also a set that defines your menu and general playback. The menu will have an entry for each of your input files; remember you can change the names before conversion.
I prefer to convert to the hard drive first. Then I double click the VIDEO_TS.IFO file in the VIDEO_TS folder to play the production on my PC. Then I can burn to disc if all seems good. To do that, click Action/Burn DVD on ConvertX's menu and select the folder containing the movie you want to burn. All of your titles (input files) will then be burned to the same disc.
