@chaintong: yes I am, and not the best signal strength either. The only times I ever have browsing problems is during those eternal waits when any Windows machine tries to access the server – during those 2 minutes, the Roku is unable to browse and fails.
@ron: well, I’ll try to disable smart playlists when the machine isn’t used for some time and I find the sqlite terms to rename the playlists table to something else temporarily, so I don’t have to enter them all again afterwards 😉
If that is the case, it seems iTunes is coded even worse than I could imagine 😀 The protocol at least allows to read playlists separately, but may be right, they’re there immediately in the client once opened, might be iTunes is reading their contents on connection directly as well.
