Tvheadend

I have been using ffdecsawrapper successfully with MythTV. But due to some problems with MythTV/Kodi i decided to try TVH. I'm building from source and downloaded the latest and have enabled both dvbcsa and tvhcsa.

Both gets enabled:

tvhcsa yes
bundle no
pngquant no
dvbcsa yes

My two problems is first that even though it is enabled, I don't get a CSA tab to do the configuration.

The other problem is that if I try to use ffdecsawrapper with TVH, a few seconds after starting TVH my whole computer locks up and I need to do a hard reset. But if I can somehow enable CSA in TVH the second problem can be ignored. Even though it is strange that it works with MythTV.

Any suggestions to what I could try? Anything else that needs to be enabled during ./configuration?
