Hi Antti,
Just to complete this I've made some tests with the
Toshiba USB DVB-T Tuner PX1211E-1TVD.
The short result is:
Without PID filter its load is equivalent to the Fujitsu-Siemens. (5.8%
and 14.4%)
With PID filter it produces even less load than the af9015 with pid filter.
About 0.5% with

I think difference comes from different USB-transfer settings.

I only tested it without the pid filter yet, and it seems to perform as
good as the siemens stick in terms of system load. So I guess it

You cannot receive all channels in the mux at the same time (at least in
case there is more than 32 PIDs in the transport stream).
is it still possible to record two stations

I am pretty sure the Siemens stick doesn't filter PIDs. The easy way to

and check if the device works with usb 1.1 or absolutely needs 2.0.
Hmm, I did't look at this page
