osmc@pi:~$ uname -a
Linux pi 4.2.1-1-osmc #1 PREEMPT Wed Sep 23 20:52:02 UTC 2015 armv6l GNU/Linux
tvheadend 3.4-1.13.x86_64 running on OpenSUSE 13.2 using a TripleStick USB card with dvb-demod_si2168-02.fw
I can watch TV from any device in the house, but the raspberry. When I hit enter om a TV channel, I get sound and a small “film camera” icon in the lower left corner, rest of menus etc remain. Ie there is no black screen, menus remain.
Before I got the USB stick I played with tvheadend on various hardware and using an older card and got picture. It was horrid though That was with raspbmc, before I upgraded to OSMC.
edit: If I record a channel and copy the file to my Raspberry and then browse to that file, the resulting .MKV file plays just fine.
edit: Updated to the latest (OSMC) version and now it works! So either was it the phase of the moon or the update that fixed it.
