I am using a Terratec Cinergy T2 USB tuner on my 266MHz NSLU2.
When I am recording a DVB-T stream, it takes around 33% CPU (zapdvb process,
the tool I use to record) but surprisingly, my NSLU2 is much less responsive
for other tasks (big latencies for ssh, fetchmail, imap and other things
that run on my box).
Nevertheless, the recorded file contains the entire stream (video is fluid).
Do you think this is a CPU related problem?
