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

[Mark Schuren]

Cool idea, thanks!

The only problem I see is that the device name of the remote control
receiver changes when the module is reloaded, is it? I already tried
this manually before, and my /dev/input/event2 device (used by lircd)
was /dev/input/event5 after the module reload... do you also have a
workaround for this behaviour? Just stopping lircd didn't seem to help.

Thx,
Mark
