Most DVD Players support playing DL DVD-R, DVDÂ±R/RW, DVD, CD-R/RW, MP3, JPEG, however different plays have their special features. You need to introduce us what DVD player you have and then we can show you the detailed video formats.
Media Center will play a DVD disk from the Media Center Application, or directly from the Disk if the DVD Drive is set to Auto Play with Media Center as default. The DVD will not play if you right click the .ifo or .vob file and choose Media Center like WMP 12 in Win 7 would. It will also play a DVD File, but only if that file is in the Movie Library. You cannot open the file with Media Center. The DVD file also will not play if it is selected through the Video Library.
