Hi. After a fair bit of messing around I managed to get iplayer and you tube etc working through xbmc. Once you skin xbmc it is a user friendly as boxee so forget boxee for now if you want flash video streaming and instead follow these instructions.
I use WinSCP to ftp/ssh to my atv box. Use the dharan (sp) xbmc install ie NOT 9.11
Thanks to Mike for original instructions. Hope this helps some other neewbs like it did me.
goto this thread and download hitchers repo: http://forum.xbmc.org/showthread.php?t=81334
ftp the zip file to your atv, pick a folder you will remember (I just put in the atvflash folder)
on xbmc goto:
system -> add-ons -> install from zip file..
locate the hitchers repo (browse to the correct folder on atv - via home and then atvflash) and click it (this should now begin to install)
give it a moment or so untill it says its installed the zip file
once thats done, go back to:
system -> add-ons -> get add-ons -> hitchers repo
when in there select:
video add-ons -> iplayer (this should now begin to download and install)
give it a moment once again untill it says installed.
go back to home and go to:
videos -> video add-ons -> iplayer
hopefully this should work!
