DVDs contain video in files with type (extension) VOB. If the DVDs are not copyrighted then you can select the DVD from Digital Media Converter and it will offer to copy the video content to your hard-drive. The copy will be region-free. Once the video content are on your hard-drive you can convert it to the WMV format for playback on the media center and the extender. Infact, the media center PC also supports direct playback of VOB files.
Digital Media Converter can convert VOB files between NTSC (used in USA) and PAL (used by Europe and Asia). This conversion does not contain the region code. The region code is added by the software you use to burn the videos on the DVD. Digital Media Converter does not have DVD burning capability. However, after converting the videos to either NTSC or PAL, you can burn them using any DVD burning software. Almost all DVD ROMS bundle a DVD burning software.
