Thanks for all the responses. Let me address one at a time.
@pkscout, thanks for sharing the XBMC plugin. Will have to check out the plugin in detail.
@dksc318, XnView looks great actually. It does not seem to be updated for a while, not sure I want to test it on a WIn 7 64bit system?
@DeathPoobar, is WMC = Windows Media Center? If so, does it do a live slideshow or did you mean I have to create one, export it then play it?
