I have started DD and switched between few channels, after few minutes, I have changed language (first and second time, not third time), DD has crashed (not immediately after language change, dvbdream1.log).
Then I started DD again and after switch to 2 channels, there was just a black screen - codec background was pink! Then immediately it was working perfect in v1.3c, same codecs, channel, setings, ch. list... After few minutes it wos working good - same codecs also in 1.4. Very strange.

Then after few minutes, I have switched few scrambled channels and DD has crashed again, this time without any error dialog (dvbdream2.log).
I'm testing Cyberlink now... Looks OK until now.

I'm using Overlay renderer, since Cyberlink+VMR9 combination doesn't work.
Changed to nVidia (a/v), VMR9 - immediate crash without any dialog after just few seconds!!
Now I'll try nVidia codecs with the old version...
Edit2:
nVidia+1.3c works perfect, tested 30 min., switching between many channels, also scrambled, then the same channel as with 1.4.
It looks the combination v1.4 + nVidia (+VMR9) doesn't work good.
Tested with timeshift disabled, in both versions.
