I could be mistaken, but I think I once determined that the horizontal pixel width of Apple's DVD player when playing anamorphic DVD's was 852 pixels, at least under OS X 10.3. But 854x480 and 853x480 are close fits as well. If my measurement was accurate (I placed an 852x480 image over the DVD window and there was no overlap), do a couple pixels get cut off or is DVD anamorphic horizontal image resolution never an exact pixel number, just an approximation? I think I may eventually check under OS 9, OS X 10.4, and Windows. I don't know about Linux or various third party software DVD players.
DVD player in Tiger - limited functionality?
My DVD Player (4.6.5 running on OS 10.4.7) won't open VOB files (though it plays authored DVD disks fine). Evidently I'm not the only one who has this problem: . I'd update the article but I'm not sure exactly what will and won't play on DVD player in Tiger. Anyone else? ntennis 06:12, 12 July 2006 (UTC)
I believe you need QuickTime Pro and/or the MPEG-2 compatibility plug-in in order to play VOB files. Obviously this will play them in QuickTime rather than DVD player - unless you put the VIDEO_TS folder into a disk image. DVD Player usually picks up the existence of the image and treats it like any DVD. --Baryonic Being 09:02, 12 July 2006 (UTC)
Thanks, but the article claims that in DVD player, a user can "choose which VOB file to open". This is clearly not true in many cases. I'm just not sure which cases! It would be helpful to have this information in the article; as it stands it is incorrect. (BTW I have QTPro and mpeg2 codec installed). ntennis 00:52, 13 July 2006 (UTC)
I am running Mac OS 10.4.11, with DVD Player version 4.6.5 as well. I have no trouble opening VOB files with DVD Player without having Quicktime Pro or the MPEG-2 plug-in installed, but the files must be in a standard VIDEO_TS or HDDVD_TS folder and in the correct hierarchy of a normal DVD. (Thus, you could open a DVD video in a mounted disk image authored by iDVD or perhaps even a VIDEO_TS folder created by a ripping program such as MacTheRipper.) The File > Open DVD Media dialog box specifically asks one to open a VIDEO_TS or HDDVD_TS folder, not individual VOB files. DVD Player can therefore use supporting chapter and audio/subtitle track information from the IFO and BUP files usually included in a VIDEO_TS or HDDVD_TS folder to enable such features in its user interface. --EssayEm —Preceding unsigned comment added by Essayemyoung4009@gmail.com (talk • contribs) 23:40, 22 February 2008 (UTC)
