Seconding bikermott... I had been using Deo VR for sometime before getting in SLR and it would occ crash so that while I could load a video from local it would not play. I installed the github LAV filters and Deo VR would not play any files after that, and after attempts at reinstalls I finally had to do a system restore to get back before the LAV filters. When I then used the SLR version, at first that worked but very high res videos and others were having trouble playing, local files would only work intermittently, downloads that had run broke, and finally wouldn't run at all--it would get stuck at something awesome loading. Even streaming would break on some files. Since they originally ran, having to install filters seemed odd, but after trying reinstalls I finally set a restore point, let the filters install to their own default directory, and now Deo VR is back to proper working order for the first time in a month and SLR seems flawless as well without having to take any other steps. So I would recommend setting a restore point before doing this but it does (thus far!) solve the problem.
