Well, this has become a nice mess; after upgrading to latest stable, my mce remote generates at least double keystrokes with every key pressed. Also the remote from my pana tv suddenly seems to work, although no hdmi cec devices are listed as input devices, so nothing to disable there.
My setup: htpc (1st gen i5 w. gt1030) on pda-v100hd with 42" pana ips. hdmi -> spdif splitter between htpc and pda-v100hd.
As an extra treat, dts passtrough isnt working anymore. I was always able to have the hdmi output for normal and passtrough use. Now on passtrough only ac-3 works, no dts. Could this have something to do with the gt1030 being all that new?
