Bioinc1234 - could you elaborate on the UPnP issues with the Library? What kind of problems did you have with UPnP, and how is SMB 'cleaner'? The more details the better - thanks!?

I might post some impressions as well since I tried to use UPnP first but was quite dissapointed.

With upnp xbmc doesn't seem to be able to even add stuff to the library thus rendering the library basically non functional when using upnp.
Btw. I used twonky media installed on a nslu2 slug.
Streaming worked tho.
SMB worked like a charm, however I would prefer to use upnp to be honest.

Same issue here. Except that SMB does *not* work like a charm. When Windows boots, you invariably get 'Unable to connect all network driives' error (I presume because the network hasn't initialized yet, and Windoze is too dumb to wait for it to be done). So, you need to use the file explorer and manually click on each of them to reconnect them again, or XBMC can't see them.

I also use TwonkyMedia; and I get the impression its buffering is superior to what a SMB drive offers. Plus, TwonkyMedia turns a collection of video locations, and turns them into a single media source: much, much cleaner than silly SMB drives to every location.
