At times my DVD & bluray drives are not recognized by certain programs. DVDs could however be played via VLC media player. The first time this happened I took it to the repair shop. He ran a program detecting filters which were ascribed to AnyDVD. When he removed the filters and AnyDVD, the problem went away. I re-installed AnyDVD with no problem. However this problem recurs routinely. Whenever the computer doesn’t recognize the drives, I have to remove the lower filters and remove AnyDVD. Do the new upgrades stop this problem? It is getting to be a real inconvenience to do this.
