Hi.
I have used Media Center for some years with pleasure. I do find a startup delay/freeze quite anoying now.
Basics:
Quad Core powerfull desktop computer, lots of memory etc. Windows 7 64bit, Gigabit network. Media (only audio) placed on external server, aprox 5000 songs, most FLAC format.
Everytime I start Media Center it works fine for maybe 15 seconds, you can start a song or look through the library, after this the user interface of Media Center freezes for about 20-30 seconds. Afterwards it works fine again.
Hopefully there is some soulution to this as it is anoying to have to wait if you want to hear a song.
Regards
