Just to clear up any confusion, here's a quick resume‚ of a few DVD points

DVD is an acronym for Digital Versatile Disk and can contain computer data OF ANY SORT.

Buying a DVD drive doesn't mean you can watch DVD movies, it means you can read DVD disks.

What are generally refered to as "DVD movies" are disks of video data that have been encoded into MPEG-II data which, even though compressed, takes up a jolly lot of room, which is why you only get them on DVD disks!

Eventually as production costs plummet, some of the bigger game titles that would've shipped on multiple CDs will no doubt be available on just one DVD.

The DVD drive doesn't decode MPEG-II data, it just reads it in it's encoded format. For the best results the decoding should be carried out by specific MPEG-II hardware, which will then overlay the movie in a Window or full screen. Alternativley, for those that require DVD Movie playback just as a secondary feature, then the decoding can be done by a jolly fast CPU using a software application such as PowerDVD or XingDVD and a jolly fast AGP display card.

...and finally, 'TV-Out' on a display card spec means it can output it's display (games/DVD/desktop etc.) to a TV (via composite or s-video) NOT that it can receive BBC1.
