Hooking up my Wii to my XP SP3 PC over a dlink wireless with fixed IPs worked, following a re-installation of version 1.8, and following explicitly entering http://, and selecting the colon from the symbols menu rather than the keyboard on the Wii (hooray). I can now see the movie files. But I keep getting an error when I try to play them back : 240020 file format video / x-flv not supported" - the movies play fine (FFd show codec) on the PC.

Just found out the /flashlib folder needed to be added. Please ignore. Thanks.
