I was tweaking one of my clients between streaming and filesharing to have a play with BBC HD on the client and the picture was a right mess, pixelation, streaking, ugh. I thought that "OK, filesharing is too slow for HD" and started the server recording the show rather than watch it live. Same result - "Network too slow then", copy file across and it was the same.
It turns out my recording drive had been, yet again, set to PIO mode in windows and HDTach was showing it as 3MB/s rather than the normal 80MB/s. The options are grey'd out in control panel, so the usual way out is to delete the IDE interface and reboot windows to re-detect it.
A bit of googling found a script to do most of it (except the reboot) and a M/S kb article that may have an answer as to why it does it.

After you suspending and resume your computer several times, hard disk performance may be reduced. If you use Device Manager to view the properties of the IDE channel towhich the drive is connected, the Advanced Settings tab may show that the current transfer mode for the drive is "PIO Mode."
