OK, it didn’t work after all. Still getting dropped frames error quite regularly (every few minutes!!!) I’m only using one FW drive, a G-RAID 500 Gig which is only half filled. I did a throughput test and got write speeds of 44 mb/s and read speeds of 58 mb/s.
I’ve re-installed the Aja driver with the latest downloaded off their site, and upgraded the firmware.
Of course, all the other things I mentioned in previous post, plus the usual “fit to window” check for viewer/canvas, etc.
Is this really a throughput problem?
