[mythtv-users] DVB-T USB dual-tuners in Mythtv?

[Mark Schuren]

Yes, that worked for me!

I used a udev link /dev/input/by-path/xxx for the lirc device (the
link was there anyway on my Mandriva box - but I didn't notice that before)
and now unloading/reloading the usb dvb modules results in a working
lircd afterwards :-)

At least it's a usable workaround for the Nova-TD / Nova-T 500 USB
stick problems - may help others as well.

Thanks for the tips,
Mark
