Hey, I wanted to post a reply to this thread to. As Tenco discovered, the MXO2 mini is now comparable with R4running under windows, I just upgraded to Arena, and discovered this thread, so i decided to give my MXO2 a try on my PC. It works!
First thing I noticed, the latency seems to be alot more than the BM intensity card I have in the same computer.
I am running R4 Arena, and my system is Win 7 64bit, I did not need to install the Enosoft DV processor, I just ran it straight from the Matrox settings in R4. I also discovered that the way a user changes input capture settings has changed, now one does not right click the cell where the capture is, but now a user must double click the capture device under inputs. when doing this with my MXO2 listed, it brought up the MXO2's setting and I just selected the correct resolution, and I was capturing my live feed via HDMI, but like i said the latency is noticeable. the BM intensity card I have in the same machine is allot better at capture in the terms of latency.
Nice work Resolume team, I love having two HD capture sources at my disposal!
