No it doesn't. The 8500, for instance, is like that, but not the 840av.

The svideo ports are those adjacent to/ either side of the monitor port. I forget which is which, but it does not have especially wonderful video capabilities anyway, so I would not get your hopes too high. It is much better at audio than video.

The separate ports on the rear that have been spoken about are RCA jacks. These are just plugs, and there is no circuit board associated (leads go directly to the logic board).
