Hi Martin, I am pretty sure the Siemens stick doesn't filter PIDs. The easy way to find out about that is to look at http://www.linuxtv.org/wiki/index.php/DVB-T_USB_Devices and check if the device works with usb 1.1 or absolutely needs 2.0. Also the system load doesn't seem to differ a lot between vdr being mostly idle and recording. I'll get my hands onto a "Toshiba USB DVB-T Tuner PX1211E-1TVD" this week. That one should have a pid filter as it seems to support USB 1.1 as well as 2.0. cheers -henrik _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
