this was our first Sunday using Proclaim. I am trying not to just bail, but give it more time. We have bren running MediaShout 4.5. So, biggest issue is video. We use several videos in our service and they are too big to sync to the group so must remain local. Problem: each one that is local lags in presentation and the audio gets out of sync with the video. Badly. Embarrassing. We finally just stopped one. Repeated attempts prior to service to deal with this did not solve the problem. Wr are running on Windows 8 with an Intel Processor 3.4GHz, 4Gigs ram, an NVidia video card that is plenty fast to run Media Shout...so it should do Proclaim, right? Any help out there? I can't find anything in the forums that really helps. We did disable the hardware acceleration. Didn't change it. Is Mac better for running this?
