BTW: I got myself a "Toshiba USB DVB-T Tuner PX1211E-1TVD" based on the DiB3000M-C/P. Unlike the siemens stick it has a pid filter. 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 uses big packets for the bulk transfers.
I didn't find that stick from code. I assume it is "LITE-ON USB2.0 DVB-T Tuner" which is sold rebranded as Toshiba (according to one comment in code). If same device then it does have PID filter and uses 4096 BULK packets.
I hope I'll have some time to test it further this weekend. Hopefully it turns out to reduce the system load by the driver to a reasonable level. If so I will finally get around to look into vdr itself as a cause of wasted CPU cycles and energy... :-)
I have very many devices but haven't tested loads yet.
