Hi SpecialK
Here is the official response to your questions:
From time to time, Discreet, in consultation with its lawyers, reviews features of its products and assesses risks involving third parties' intellectual property rights. As a result, we've decided to make certain changes to a number of the Discreet products. Pending further legal review, we are under instructions from our lawyers to not discuss the matter further.
I apologise but it is a legal issue as mentioned above..
As for the black frames occuring I have not seen this problem. However I suggest you flush your cache. This can be done by right-clicking on the small RAM Meter at the bottom right of the screen.
