1. Surround sound. Where the fuck has it gone? Vista has completely done away with any kind of surround upmixing by obliterating DirectSound thanks to its "incredible new audio system". Well isn't that nice, my 5.1 setup is utterly useless now. Kudos

PS. Fuck Creative's ALchemy. It doesn't do shit for movies and music.
2. Ridiculously slow file transfer speeds. I'm talking 3-10MBps file transfer speeds here. It doesn't matter whether files are being transferred from local hard drives, external eSATA, or a DVD - it's unbelievably slow. I've tried everything, from disabling Remote Differential Compression to enabling advanced performance on the drives and selecting a high performance power plan. No change for the better.
