Hi David, I have an AthlonXP 1500 with 1 PVR250 and 1 PVR350, without any hard disks at all, connected by a 100base switch to the main server. I haven't had any problems caused by running out of network bandwidth - even with both PVR's recording a program, and running a mythtranscode. That is 2 x 4mbit/sec for the recordings, plus 1 x 4mbit/sec and 1 x 1mbit/sec for the transcode. I am using NFS v3, over tcp, with tweaked network buffers (see the NFS howto for performance tuning onfo), with a recent 2.6 kernel. Considering the maximum bit rate from a 350 is ~ 12mbit/sec, and doubling that for overhead - for a single PVR350 you would only be using approx 75% of the theoretical maximum of a 100base switched network. Another data point is that I have fairly successfully run a myth live-tv 3mbit/sec stream over an 802.11b network (about 5mbit/sec max in my setup), albeit at a reduced resolution than my wired network. <snip> HTH, Mark -- Mark Cooke <[EMAIL PROTECTED]>
