I have recently joined being a Boxee addict and instantly "supported" Bartsidee's repository. This repository should be one of your "default" installs:-) Especially the excellent Music Player that fully supports your musiccollection ID3 tags (Boxee by default only recognizes albums and artists).
Recently "Bartsidee TV" has been launched. Viewing UZG et all works like a dream but.... only once: After searchresults were displayed and you picked your choice for viewing I can't start a new search when viewing has finished. (Restarting the APP is the workaround). Will this be fixed in a future version?
