Well i would search for new networkcard drivers. You can even look if there are some settings for tcp checksumm offload.
I don´t think its a problem with the tv-cards handling. But if you stream to three clients that costs some cpu usage. No CPU usage for that would mean take the complete transportstream and trow it on the networkcard. But that would fast get you into bandwith trouble. Next option is to look for new sata/ide drivers. Because all timeshifting or recording is made over files on the local harddrive. Three clients means three timeshifting files.
Back to the network. My Scaleo E has a Fireport. I thought no gigabit ethernet why don´t feed the system over firewire. Ok so i installed a ftp server and connected my notebook via firewire to the host. Well coping files over that firewire port via ftp causes my livetv to stutter on a single seat machine that has a 3,2Ghz Pentium 4 Prozessor with DXVA enabled grafikcard i got 100% CPU usage while copying with about 25 MB/s. My harddrive can write 100 MB/s. Even recording 9 Channels at same time is no problem for that machine!
Well things you can try for your server. Grab an old scsi disk for timeshifting! If your server can make some noise take one with 10000upm. Those scsi drives don´t cause any cpu usage and are cheap todays. I would recommend one of those IBM-DDYS drives they have an fantastic seek time of 4,9 seconds and aren´t that loud
The seagate cheetahs are even fine, but very loud and the sound like someone put some sand in them
Or test another networkcard that can make differences. Most onboard cards from broadcom. I haven´t got ever more than about 40% of the 1Gbit between to windows servers. Ok some peaks reached 80% but most of the time they are slow and cause high cpu usage. 50% CPU Usage for 40% of the Gigabit on a Dual Xeon 2,8Ghz System is too much. So i started using intel cards the make a much better performance at lower cpu usage. Even the 3com one are fine. But they aren´t cheap. Ever ask why the Intel cards cost that much? Thats the reason!
The can reduce cpu usage by making the checksumm offload itselves!
