I had 0.8.6f (some old version) but it stopped working (probably a QT upgrade).
I upgraded to the latest source one (and also tried the Gentoo build which is the same version but maybe an older snapshot).
The video is really slow and not working right but what was obvious was my lack of sound.
I thought I had an audio passthrough option for output that is gone in this version.
I used direct audio passed to the motherboard and the SPDIF to my receiver (bypassing audio software).
