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 zap and 9.7% with an idle vdr.
Since managing all those numbers starts to get confusing I've put them
together on my page at the linuxtv wiki:

I hope I'll be able to add some more receivers.
cheers

PS : I'll attach the results of the toshiba stick in order to get it
archived with the rest of the thread.
