How to read vob, ifo, or bup DVD files?

If they are true DVD files which it looks like they are then use +DVD Player.app+. It's in your applications folder.
Open DVD Player and press ⌘O, a dialogue box will appear. Navigate to either the folder containing the VIDEO_TS files or the DVD parent folder itself and DVD Player will play it.

Two things I would try then, if you have toast burn the DVD to disc and see if that works or use [VLC|http://www.videolan.org/vlc>.

You're not selecting the actual VOBs themselves are you because they should be greyed out?

No, it's just the easiest and most well known option. As far as I know you cannot just burn VIDEO_TS folders to a disc and hope it'll play, hence my suggestion.

But try VLC first if you haven't already. But I've edited my last post-have you re-read?
Gotta go out for a while now-C ya.

The VOB, IFO and BUP files should be in a folder named VIDEO_TS. If you drag the VIDEO_TS folder to DVD Player's dock icon, the movie should play. You can make a DVD from the VIDEO_TS folder using DVD Imager

and Disk Utility.

Sorry, that's a big negative.

It should though. Just tried it. Maybe you need to drag DVD player prefs out temporarily. Or something amiss with Launchservices perhaps?

Just read somewhere here another problem with launching apps. If you have Cocktail, rebuild the Launch Services Database.

wow i didnt think this would work on mine but if you go to file snd open dvd media on mine and choose the TS_ folder it plays it like a dvd

Yup, normal in this version of DVD Player. One of the earlier builds you actually had to drag/select the entire DVD folder.
