Hi trythisthen,
Have they just stopped working automatically or have they always not worked?
If they have just stopped working then the chances are that the autoplay/autorun option has been disabled in the registry - Windows occasionally does this for some unkonw reason.
If this is the case take a look at this link from my website: http://vistasupport.mvps.org/autorun_autoplay_don't_work_when_cddvd_is_inserted.htm
