I just upgraded to version 188.8.131.52. My playlists were working fine before this and now they don't work. When I play my playlist, I get the following message after each song: "Opening URL.....Rebuffering Stream" and it stalls. It does not go to the next song.
I have my songs on a different PC and use the Home Sharing functionality to share it across my wireless network in my house. I am connected to the Web via cable. I tested the speed and it's 20.54 Mb/s. My Quicktime settings are as follows: Streaming Speed is 1.5 Mbps/Intranet/LAN, Instant-On is enabled. I tried it at a streaming speed of 1.0 Mbps and the same thing happened.
Within ITunes, my Streaming Buffer Size is set to Small.
