Hi, I was in the process of setting up my machine so I can run any of the tests you might ask for. First I needed a fully tested backup partition, and then I needed to bring udev up to date. But I see that the problem is pretty much resolved right now. As Devin said earlier I doubt I can ever

Andy, This is a great answer! Thanks very much. When I get into this situation again I will know what to look for. A possible reason why I got into this problem in the first place is that I tried many combinations of parameters with mplayer and azap in order to learn how to use the USB tuner i

Hi, I tried something simple with three kernel versions: 2.6.30, 2.6.31, and 2.6.32.7. But I can't reproduce the problem that way. Just after booting I run alternatively /opt/dvb-apps/bin/szap -a 0 -r "CCTV 4" /opt/dvb-apps/bin/azap -a 1 -r "57.1" and then I run them concurrently and finall

Hi Devin, I was previously running kernel vmlinux-2.6.29.5. I notice there was a major reorganization of some of the media structure between 2.6.29 and 2.6.32. Can you tell me at wich kernel version the change occured so I can start from there. Richard Devin Heitmueller wrote: On Mon, Feb 8,

Hi, I got some driver crashes after upgrading to kernel 2.6.32.7. It seems that activating either TBS8920 (DVB-S) and HVR950Q (ATSC) after the other one has run (and is no longer in use by an application) triggers a driver crash. Each device individually works fine (as long as the other one doe
