Hi all, I have an Ubuntu 9.10 fileserver running samba upstairs, which connects to a Homeplug adaptor which funnels the network downstairs. My HTPC running Windows 7 is downstairs, also connected to a homeplug adaptor. When playing a 40-minute MKV file (served from the fileserver) on the HTPC, the network speed hovers around the 330-400kbps level, and the video occasionally stutters. However, when you copy that file over the network, it takes 12 minutes, and the speed goes up to 12-15Mbps. If the Hardware is capable of sustaining that transfer rate for copying, why not for streaming? I'm wondering if it is network dropouts causing it, but nothing suggests that on Win7's Network resource moinitor. I've tried turning the whole network off and then on again in the correct order, but it doesn't seem to have changed anything. Any Ideas? Update: I've determined that it is a Samba issue, as it happens on all PC's that stream video from the fileserver.
