I'm also using a PCTV nanostick 290e to multicast the DVB-T2 mux too. I'm having a problem with the Nova-TD sticks (52009) using recent builds from the media_build git repository (to get the 290e drivers) on Debian squeeze using 2.6.38-bpo.2-686. The problem is that only one half of each Nova-TD stick will tune and give data. Which half seems to be random and changes with each reboot. Occasionally I'll get a whole stick working or one of the sticks will not work at all. If I try to use a non-working half of a stick it will knock out the working half until I stop using trying to use the non-working half. So I'm seeing interference of one logical dvb adapter from another that are both on the same physical hardware. Also after a few days the sticks stop working completely and need to be powered down before they work again, but this may be a different issue. I'm getting a few "dib0700: tx buffer length is larger than 4. Not supported." in dmesg during first tune. Maybe coincidence, but I've noticed that on the last reboot 4 tuners (out of the 6 total Nova-TD tuners) are not working and I have 4 of the above message in dmesg, so there could be a link. I've tried turning on the debugging for both the dvb_usb_dib0700 and dvb_usb modules but there was no indication of the problem. Any suggestions for what I could try next to find the cause and fix this?
