I explain with a 1-10 step:
1 - create a title with TDK (F2)
2 - save it to Liquid (F11)
3 - move the title into sequence
4 - apply the crossdissolve using the dedicated key on the keyboard (italian is the 'à' key) or the crossdissolve tool on the toolbar
5 - exit liquid
6 - open liquid again
7 - move the title in sequence or create another one and put it on sequence
8 - apply the crossdissolve again
9 - dark red slice appears in corrispondence of the crossdissolve
After this trouble it is also impossible to assign a custom transition FX as DVE default. An error massage appear telling that 'it is "impossible to write on SYS".
But if i drag and drop the crossdissolve manually from the library than it is all ok.
All this only with a NAS configured with Raid 1/5/10. If i try with Jbod, Raid0 or iSCSI then all is OK. I also try using one of my Ubuntu Linux system with a single system disk and have no trouble.
I'm ripping my hair from the nervous. And the same problem trying with Openfiler (free NAS system). Tomorrow i try with Jbod and Raid0 on Openfiler and let u know.
If you wish i can make same screenshots.
