Yes, that would be software decoding. Unless the nvidia fx5200 somehow
is used to help out.
The frontend is doing something like this when watching live tv:
top - 12:57:27 up 7 min, 2 users, load average: 0.93, 1.49, 0.81
Tasks: 114 total, 1 running, 113 sleeping, 0 stopped, 0 zombie
Cpu(s): 51.0% us, 4.5% sy, 0.0% ni, 40.3% id, 0.3% wa, 1.0% hi,
2.9% si
Mem: 256344k total, 251232k used, 5112k free, 0k buffers
Swap: 199992k total, 0k used, 199992k free, 99284k cached

Look at the total cpu usage on the frontend as the process list does not
seam to be completely correct.
When watching xvid movies and alike it run up to about 70-80% total cpu
usage
.
The pvr250 has an mpeg2 encoder otherwise the P3 would not be strong enough.
As to network traffic, the system report somewhere around 1Mbyte in both
directions when watching live tv. The gives no real load on the 24x4
server, which by the way uses lvm striping over 2 disks, and is able to
deliver 5-8Mbytes (writing-reading) over the network.
Live tv pause, does not load the system as much as live tv watching, as
pause does not require reading from the live buffer.

Are you using software decoding on the P3 733Mhz? Can
that setup handle live TV pause?
I am thinking of having an old laptop with almost those
specs to be one of my front ends.
Thanks,
