I can confirm that I'm seeing a very similar issue (minus the problemswhen unplugging and reconnecting the device) with the same hardware.However, I have only one slave device and no master devices, so I'm notable to test in Windows - of course, the slave device should workwithout restriction (in theory!) in Linux. With a manually-created "channels.conf" file for the UK / Crystal Palacetransmitter (verified with another card) I'm able to use tzap to tune to"BBC ONE", and I receive the following output: -------------------------[root@languid adapter0]# tzap -c ~aclark/channels.conf "BBC ONE"using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'tuning to 505833330 Hzvideo pid 0x0258, audio pid 0x0259status 00 | signal 400f | snr 0000 | ber 00000000 | unc 00000000 | status 1e | signal 000f | snr cbcb | ber 00000000 | unc 00000000 | FE_HAS_LOCKstatus 1e | signal 002f | snr c9c9 | ber 00000000 | unc 00000000 | FE_HAS_LOCKstatus 1e | signal 000f | snr cece | ber 00000000 | unc 00000000 | FE_HAS_LOCKstatus 1e | signal 007f | snr cbcb | ber 00000000 | unc 00000000 | FE_HAS_LOCKstatus 1e | signal 000f | snr c6c6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK------------------------- The channels.conf file is as follows: -------------------------BBC ONE:505833330:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_3_4:QAM_16:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:600:601:4164------------------------- Once tuned, "dvbtraffic" produces no output.

I have seen it work in the past in Windows, as at onetime I did have a DigiTV PCI card (which is a master device by defaultin terms of the Nebula software), but the PCI card stopped working longago due to a hardware fault. I do wonder if the problem might be with the firmware. However, that'sonly a hunch and I have no way to confirm either way, mostly becausedebugging something like that is way out of my league. :) Mark - Maybe you can do some of the above tests if you haven't alreadyto try and confirm if the issue is consistent for multiple slavedevices.
